Title: Rockman's new ride
Post by: rockman on March 18, 2016, 07:24:24 PM
Just brought home an '03 Rubicon. It's a project that will take a while. No issues with the blue Jeep, just planning ahead and many thanks to Corey cause Rubicons are hard to find. It came with a 4" lift, good custom bumpers and a 9K Warn winch. It needs tires and has some rust issues but the frame is fine. Just looking for a TJ that is good in the woods as well as the highway on 35s.

I'm really happy that worked out for you.   I would have liked to have bought it!  Looking forward to seeing what you do with it.

Finally got the Jeep on the lift today and checked it out and it doesn't have any evidence of being in the woods. It was owned by a woman who used it as a DD. Looks like a week's work to prep and paint the whole underneath. It's going to need tires and wheels, gears and at least a front locker and a tummy tuck. It'll take a few months with all of the small tinkering.

Finally got the underneath all painted and the fluids changed. Decided to stick with the Km2s. The tread on the 35s is only 8.8" which is only .8" more than the 10.5s. The Km2s really aren't that impressive looking but the magic is in the casing, I've seen these tires do some impressive things. Funny thing, I've still never tried a TJ with a 6cyl., with 35s or a Rubicon, should be interesting. By the end of the week I should be able to try it out with at least 33s. Still will have to build tube fenders and the tummy tuck will be a bitch. Right now the skid pan hangs down 4.5" below the frame. :nuts:

Yesterday was a good day, got to take the Jeep for a ride on the road for the first time. Tried the 33s first and then the 35s. There really didn't seem to be much of a difference in gearing or power. With the stock 4:10s the road gearing seemed fine and low range is very low so gear changes won't be necessary. The 35" Km2s are more aggressive than the 33s. Bigger knobs and spacing. I went with 8" steel wheels with 4.5" back-spacing, that keeps the Jeep as narrow as possible. Nothing appears to rub with simple testing and the tires will work with the stock fender flairs. The Rubicon has air lockers that run on 5-7 psi. It has 2 air pumps about 4" long located behind the t-case and the rear also has a gear driven LSD. I'll give the front locker a try but it's most likely going to get a Tru-Trac. Plenty more tinkering to go.

If you remove the front locker hang onto it.   A lot of guys put them in the rear axle.  The stock rear locker is weaker than the front due to the limited slip and prone to failure.   Also I would recommend relocating the air pumps under the hood.

Finally got the winch hooked up that came with the Jeep. It's a Warn XD9000i and it doesn't work like they said. The electrical side is packed with blue corrosion. This would look really good on the front of a mall crawler but now I need a winch. Going Jeeping without a winch is like going shopping without pants, not good.

I do business with a guy who fixes starters and alternators and we'll see what he thinks of it. This winch sells for $1,350. new which was a plus for buying the Jeep. A winch is something that needs to be dependable.

Yeah they are a great winch.  I had one years ago on a YJ.  Im sure it wont be too tough a fix.  Clean/grease the planetarys, new motor and an albright contactor would be a great upgrade.

That's exactly what I did with my 8000 and so far it's held up.

Finally got the Rubicon on the trail this weekend. The Trutrac got put in on Friday just in time. Two days of hard wheeling and the Jeep performed much better than expected but the stock skid plate is designed to snap onto big rocks and not let go, NFG. Also,the front tires jam hard into the fenders so there's much more work to do.
Title: Re: Rockman's new ride
Post by: djljeep on June 08, 2016, 09:59:25 PM
I didn't even look this weekend.  Is the winch a XD9000i or one of the thermal overload protected 9.5cti things? 

I know people have issues with the thermal protected things, but If it is a XD9000i, they are a great winch, and also pretty simple.  If by "electrical side" you mean the motor, then it is worth replacing or having rebuilt.  I put a replacement motor and planetary housing on the one on my Dad's TJ.  The trick to those things is giving the solenoids a good, solid ground connection, and only applying a thin coat of grease to the sun gear in the planetary housing.  Over greasing is what makes the freespool lever hard to use and also makes free spooling next to impossible.

I also recommend rigging up a cab control.  If wired the right way, it can minimize the solenoid clicking problem.

It is the XD9000i and I took Corey's advice and put on a new motor, works great.

This Jeep is an experiment with dual LSDs and a selectable rear locker. The first 2 day ride had some mixed results. The handling was great and the traction was good but a front tire wouldn't power over a rock a couple of times. I need to try tapping the brakes when this happens as it says in the directions. The rear LSD worked well enough to make the locker totally useless both days. Whenever it was clicked on for some assistance it never made any difference. My first ride started out with a muddy climb following 15 Jeeps so I kept the locker on. While struggling to climb I shut off the locker and it drove right up. Later on it did the same thing on a steep ledge. :nuts: It needs more testing.

Been driving the blue Jeep because this one has never handled well. Every part on the front end has been replaced. Just replaced the front lower control arms with adjustable ones. When this Jeep had a 4" lift installed with the stock CAs, it rotated the front diff 1/2" and threw off the castor adj. Finally it handles well.
Title: Re: Rockman's new ride
Post by: rockman on October 17, 2016, 06:24:06 PM
With dual LSDs this Jeep was a dream to drive off road but the front Trutrac had only 90% as good traction as a locker. The good part was that it would easily steer any place it was pointed and it felt like it had super heavy-duty steering. So I took out the Trutrac and put in a Detroit locker. Too much traction and I lost 1/2 of the power steering power and it has too much pressure on the steering wheel, NFG. Next step is the tried and true Aussie locker, I was just looking for something more HD. If anyone is looking for better off-road traction for a DD, I'd highly recommend the Trutrac front or rear, that thing is sweet!

I'm looking for more abuse, the Rubicon is getting a belly lift. Bought a 1" skid from Undercover Fab which should be a 3 1/2" gain. A project like this takes time. All 6 pan bolts snapped off so I ordered some nutserts from Black Magic Brakes, it's the only place I could find them. Had to go with taller motor mts. so those are ordered. The first thing to install is the Novak cable shifter but UF forgot to mail it. After this project is done I'll have to measure and order a new driveshaft. While waiting for parts I tore apart the rear diff. This Jeep has always had a dry sounding bearing somewhere so I changed the diff. bearings. They had wear but no smoking gun. The axle bearings are new so I'm thinking pilot bearing?
Title: Re: Rockman's new ride
Post by: yamaha225 on February 28, 2017, 10:11:07 PM
Just my humble opinion but when the skid bolts snap off I wouldn't replace those foolish nutserts. It's not a bad job to make up a piece of flat plate as wide as the bottom of the frame and drill 3 holes in it. Then weld 3 nuts to the backside so they are welded the entire way around. Then just cut out the section of the bottom of the frame and replace it with your new piece. The nuts will never spin again and as long as you gob them with anti-sieze they should come out ok. Just my opinion though!
Title: Re: Rockman's new ride
Post by: rockman on March 01, 2017, 03:26:07 PM
Somebody put nutserts in this previously and they held up fine, they just didn't use anti-sieze. We can fabricate but I like easy.

Finally got the belly lift done. It looks good but it came with a full can of worms. Had to re-engineer the exhaust to get the transfer to lift 3". Had to bend the shifter to keep my knuckles out of the dash. Needed a 1" motor lift. The Jeep has a 4" lift plus a 3" belly lift which makes it 7" higher than stock for the short drive-shaft. I put on a funky looking low-profile trans. mount which brings it back to 6". After cutting both upper control arms, the diff. was rotated 1.5" to line up the pinion shaft with the drive-shaft. The new shaft is maxed out but haven't tried it yet.    .

Finally figured out why this Jeep eats rear axle seals, the axle is bent. A new axle and all is good. I was on the Grafton Notch trail on Sunday and the throw-out bearing started screaching. Twas a long way from home but it stayed quiet at highway speed. The tranny is out and a new clutch kit is going in. This Jeep sees lots of miles on weekends.

Glad you got it home ok Rockman. We were at Schoodic Saturday. Good trip but it further confirms how bad I need a belly up. Especially being on only 33s. Control arms and a plate are the next money. Gonna try it with 33s a while though, I think.
Really like your setup though.......

Been fooling with compressors again. The Viair was too slow and the ac pump conversion turned out better but not good enough for 35s so the Viair got put back in tandem with the other one. The result is excellent, it will now hold steady at about 100 psi instead of 50. Here's my take on air tanks: they help if you have a good compressor but not if you don't. Previously my tanks would empty out in seconds and the little compressor would struggle to fill the tire and the tanks at the same time.

Good info. I was going to do an AC compressor on my last rig because it did not come with AC. I really dont want to give up the AC on my new ride so I need to look at something else.
Title: Re: Rockman's new ride
Post by: djljeep on April 08, 2018, 10:29:54 PM
To your point on tanks - they don't help much at all for airing up, I used to run the York in my CJ5 without a tank at as well as the Sanden in my Dad's TJ.  Where the tank helps is when you have to pop a bead back on or run an air tool (which I'll admit isn't a requirement for everyone). 

I've also found that raising the RPM just slightly makes a dramatic difference in compressor output.  During Jamboree I tach up to A high idle on my hand throttle and I'm done airing up in less than 5 minutes.

Glad you got it worked out Rockman. I struggled with what to do also. I ultimately took a chance and went with a Powetank. I've been very happy with it. Plenty of capability. It airs up extremely fast, and I like the ability to take it with me in the truck or my wife's car.
In the 5 or 6 years I've had it, I've never had an issue with capacity.  I can see where one might on extended, expedition like trips though.

It appears that a good portable is a good way to go. The Viair is pricey and only puts out 1.66 cfm @ 0 psi. It also wants 23 amps and I'm told that these Jeeps don't put out that much. Replacing the ac pump with a York is still the best way to go but mine is located on the bottom of the motor where you can't even see it and the York is tall.
Title: Re: Rockman's new ride
Post by: djljeep on April 09, 2018, 05:41:56 PM
On 4.0L Wranglers York mounting is difficult due to the AC pump location but on 4 bangers and cherokees the pump is right on top and is very easy to mount either style.
