88 YJ Total Rebuild

Its a 88 YJ Laredo with a 258ci and automatic trans.



















Got started tonight on the tear down.



Topless



Hood, fender flares, seats, carpet, and tires gone................



Inside tub pretty good except for the drivers side floor.





All in all pretty good progress for one evening worth of work.

Today I dropped the belly pan and warmed up the engine to try and find leaks. It would be easier to tell you where it doesn't leak.

After that I pulled the plugs and did a compression check in each cylinder. I was very surprised from the results. 4 cylinders had 140psi and 2 cylinders had 150psi. Well with in the specs.

I did notice that all the plugs where 1/2 light gray color on one side and brown on the other?????

Looks like a total rebuild is not needed, but a full new gasket and seal kit is for sure. I guess after 25 years, isn't too bad.






Next will be remove front fenders, grill, and then the tub.


Matt

Miles are low. Definitely no need to rebuild.

Frame seems really solid, just scaly rust that i can see on the frame so far.

I did manage to get the fenders, grill and radiator off today. Also labeled and unhooked all wires, hoses, and linkages between engine and tub. Got all but 2 of the tub bolts out. 2 snapped up inside. Gas filler neck, exhaust hanger, E brake, and transfer boot unhooked. From what I can tell, I should be ready to pick the tub off tomorrow.

Managed to get the tub lifted off. I did miss the 2 bolts in front of the gas tank on the first attempt.

My leg started hurting for some reason I don't know so that is it for today. Bad enough I only have one arm, now I'm down a leg too!

My 17 yr old son flopped his Liberty on its roof on Sunday, so I will have to help him get it back to a driving condition when we get parts. He is ok, just a life lesson on driving on icy roads.

Next on the YJ will be pulling out the motor/tranny.

I like where this rebuild is going, brings back memories of my 87'. Glad your son is ok, keep up the good work.

This morning I went looking for the diff ratio. The rear tag was missing completely and this is what I could salvage from the front.



Any Ideas on what I have here????? 3.70????

I did get the Transmission/Transfer Case and Engine out today.









The engines new home for a while.



I sprayed down all the suspension bolts down with Knocker Loose spray, and will let sit overnight like that. Going to start with dropping them off the frame tomorrow.

Thanks guys. Not too concerned what's in there, I know they will have to come out and like 4.10 or 4.56 go in to step up to 33's.

Thinking about converting them to 30 spline and installing lockers.

Had a good day in the garage today, except for just about every bolt I put a wrench on was froze tight!!
Ended up cutting quite a few with the cut wheel. So I will have to drill out and fix some of those that are in the frame.



Well we are down to the bare bones now!!



Next I will start cleaning up the frame and make repairs to that.

I still don't know exactly what direction I'm going to go with this yet. I'm open to some ideas. Nothing too outrageous though. I like 33s or 35s, so will have to figure out lift options and gearing/drivetrain for that first I guess.

you lucky dog I am totally jealous of the amount of space you have in your work area...I am doing basically the same project in a one car garage with very low ceilings and it's a PITA

this is pretty much all the indoor space I have to work in....as you can see I can't have my rollbars installed or windshield frame up while it's inside
