Engine swap

Thinking of getting rid of the 4.2 in the 89. Should I just do a 4.0 or should I throw something else in there? Whatever it is it's gonna be fuel injected.

Pilot bearing direction

One side has a seal, does it go towards the crank or the transmission?

Got My Blue Turd 89 YJ Back on the Trail

Over the winter I put this in the garage with the intent of putting new B pillars, changing the transmission (again) and regearing the axles (44s).

The drivers side ended up being way worse than I thought. Not rust but it was all tweaked from either rolling over or backing into a pole or something. I ended up cutting the whole side off and poorly welding in a new quarter panel.

Finally in June ... winter project ... I got around to regearing it. The front faught me big time. Someone attempted to regear it very poorly. Had to take it apart and adjust shims >20 times before I finally got a good pattern with backlash. The front got a locker. Rear did not.

Now to find spare parts and figuring out the steering setup.

Running Wire Through Upper Roll Bar Pad

Hi everyone,

I’m currently in the process of installing a dash cam in my 93’ 6.0L. I’m using a vantrue hardwire kit. In an effort to make it as clean as possible, i’m attempting to run the USB-C wire through the roll bar pads. I have it up through the zipper one, going vertical, now my problem is running it through the pad that goes next to your head. I’ve tried using a coat hanger but it keeps getting caught on the inside foam. What i’m asking, is can you remove that specific pad, without cutting it? It does not have a zipper on it, like the pads behind the passengers do.

Edit:

With a night of sleep, I went back with tape and a longer coat hanger, and I got it!!! Thanks for the help.

Thanks for reading!

1 inch body lift.

Entertaining the idea of installing a one inch body lift. While looking I noticed there are two different types. The first is the style I've seen before where it is basically "puck" or spacers to use with the orignal body mounts. The second seems to just make the body mounts 1 inch taller so it's basically an "intergrated" piece such as rough country's. Are there any pros or cons to using the 1 inch taller body mounts vs using spacers? Thanks in advanced.

Fender flaires, what do you use?

Hey. I just got my first YJ. And my fender flaires are painted in the same color as the body. White.

One of them has a big gash in it, and so needs replacing. The seller actually had the spare fender flaire for the one with the gash, so i won't need to buy a replacement myself. Thats great. But it's black plastic. Which will need to be painted.. and the other ones, also have small chips and cracking in the paint, so should also be repainted or something.

However, i quite like the black contrasting fender flaires on a white Jeep. So I want to make them black. I plan on taking them off, to remove the white paint. Not sure the best method for this...

And then i guess the best way is to paint them all the same shade of matte black? But I thought, maybe just maybe I could paint them with a bedliner spray or something? Will that look ugly? I just thought i stead of the bare black plastic that fades over time, it needs some sort of paint or other coating on it. And would bedliner work? In my mind it would give some level of protection from rock chips and such, compared to regular paint. Maybe...

Any ideas? Also, should the sidestep be the same color as the flaires? Mine is currently white, but with a black step protector installed. But would it maybe look better and more cohesive with the whole sidestep being black too?

Cannot connect transfer case shifter

Sorry for the footage I was under the dash with one hand. I keep trying to put it on but it won’t attach. I Can get it on like an inch then it won’t go in anymore. Don’t be dirty minded UPDATE: got it on but is still very woobiley so I’d don’t think it is secured and I can still pull it off

Help tuning 1987 4.2l Wrangler

I'm in over my head guys... my buddy brought me this car saying it stalls when put into reverse. I thought, transmission issue? Easy! However, I figured out that was actually not the issue, but the engine/tuning.

Unfortunately, I'm a diesel mechanic, I have never done anything more to a gas engine, let alone a carbonated one, than replace the spark plugs and call it good. So that's what I did. I pulled the plugs and they definitely looked bad. The gap was ~ 0.050" which is substantially more than the manual specified 0.030". They also had pretty bad carbon build up, which from what I read is either rich mixture or retarded timing.

Anyways, I replaced the plugs and it already sounded a little smoother in the exhaust, however I don't feel right turning it back to him, knowing there are still issues. So I am determined to try and get this thing tuned right. But as said, I have no clue what I'm doing...

I read some stuff, watched some videos. I know there are two screws on the bottom of the carb for idle. There is also a curb idle and fast idle screw on the top driver's side? I couldn't figure out what those are supposed to do. I guess I also need a vacuum gauge and a timing light??? Not sure what that is...

Anyways, if anyone has a video or thread on how to do this, step by step, or would be willing to walk me through it even, that would be great. Unfortunately, as bad as I am with this, my buddy has 0 mechanical capability, so he's gonna end up having to pay a shop if I can't do it.

Any help would be amazing!
