Hey, i have a noise in my front end, starts right when i start rolling, and doesnt stop until the brakes are applied. Pretty much a Thump thump thump thump. Gets faster when going faster, any ideas? drive shaft joint? axle?

 

SYMPTOM/CONDITION

Some 1988 Jeep Comanche, Cherokee, and Wagoneer built between 01-20-88 and 06-23-88 equipped with front axle disconnect system, may experience a knocking/clicking noise at road speeds between 25 and 65 mph in the 2WD mode only. This noise condition is the result of machining tool marks at the differential end of the intermediate axle shaft.


maybe this, i have All Data at school I'll have to look into it.

 

Although i do have 2 different size tires front and rear, but i havent engaged 4wd. can anyone chime in on this?

 

could be the axle u-joint too...front hub bearings even? :/

 

could be a u joint, im going to check them tomorrow! thanks for the reply

 

ya..get under the truck and have somebody rock it forward/back..you will hear it. When was that greased? check if you see rust. Happened to me..took it off and it was dust in the caps and some bearings fused up to each other.

 

I'm unsure i just got it about a month ago, didnt bother checking the joints cause when i test drove it it was fine. Guess ill find out if there bad tomorrow

 

First of all put the proper size tires on teh front, a difference in size and pressure will cause problems on 4wd vehicles.

 

i know, thats why i havent put it in 4wd...

also i figured it out, the ds is fine, wheel lugs werent torqued on enough
i feel stupid.

 

i am having the same exact issue and my first thought was to go straight to the u joints

 

I also had the same exact issue. I greased all the bushings, etc, and it went away. I don't know which one the culprit was, but as someone else stated above, try greasing everything.
