My 1988 jeep comanche 4.0 4x4 auto died on me over xmas break in my home town 2 1/2 hours away. long story short it was the cps. Left it there, got it repaired and ran fine. went to drive it 2 1/2 hours home tonight and got 1 mile from the house. I was slowing to a stop maybe 20 mph coming to a stop light and all the sudden my tires locked up and i came skidding (Storming bad also) to a stop and slid into the oncoming lane.

It was still idling when it came to a stop fine. it was in drive, then pressed the gas and it wouldn't go anywhere. Reverse however worked. I had to reverse off the road through a ditch to get to a parking lot. I got stuck in the ditch, then tried 4wd. It wouldn't engage though, The tried drive and it went in. shimmied my way unstuck and felt it starting to sink again in the mud so i tried 4wd again and it worked. then reversed in 4wd out of the ditch and over the curb into the parking lot.

After all that I got out looked around and everything seemed fine on the truck and drove it straight home?!?!?! no noises or anything really!!!



WHAT THE HECK HAPPENED?!?!!?

 

the truck has been converted to 4x4 by the PO. the engien has 105k on it. I have a 1991 np231 unknown mileage, that just had a sye installed with a tom woods drive shaft professionally and he said the transfer case looked very good inside. and I know nothing about the transmission.

 

Ummmm...... Rear end locked up?

 

Not sure it was the rear end or front or both. It happened so fast.

 

It was very loud and violent and it was not just the rear breaks locking up and coming to the stop because it was wet. That has happened to me plenty of times before in other cars. Is it possible the trans tried to down shift and locked up or Somthing?

 

By rear end I mean the gears in the rear end. Like a gear tooth has broken off at some point and it got stuck in between the ring and pinion. If a trans locks up it won't work again....and usually requires picking bits up....

 

x2 on the rear axle.

I've had the exact same thing happen.

Twice, actually.

I'd be willing to bet your pinion bearing seized, exploded and now the pinion is in there cocked sideways.

Go take a look at your pinion.

Just swap out the rear axle. Much easier and cheaper than reworking the damaged axle.

(Ya shoulda lowered the back down.)

 

Ok so I'm going to pull the rear diff cover off then. I already have a 8.8 with 4.10ssitting in the garage just have got the bracket kit to put it on and still trying to get together stuff to regear the front at the same time.

 

Sure enough the truck did it again and had to crawl home in 4x4. Pulled the diff and found all these goodies!

 

Ah! Cross pin came out. That happens too. That axle is junk. Get a different one in there.

 

one step a head of ya

Went to the junk yard last week and scored a 97 explorer 31 spline 8.8 with disk brakes and 4.10 gears for 200$ Wahoo. Now I can get rid of the TURDYFIVE!!!

The load and unload was intresting to say the least.....
