Need help….

[03 KJ Gal]

Can someone please guide me as to where the heck the motor mounts are on an 03 KJ.. I’ve searched everywhere and no clear answers. Also would a broken motor mount cause a clanking noise in the rear at acceleration. Thanks in advance

if it is coming from the rear, it is usually the Upper Control arm in the back - attaches from the body to the top of the punkin.

might also be the lower control arms. Those were recalled on kj's. Yours may or may not have been done. Need to call dealer with vin to confirm. i think you can also search open recalls on car fax or edmunds.

Thanks so much. I’ll definitely check into the recall

Clunk on acceleration can also be a bad driveshaft u-Joint, typically the joint right at the rear differential.

Wow that sounds bad. Is the u-joint replaceable or do I have to replace the whole driveshaft

99% of the time the u-joint is replaceable. If the yoke on the driveshaft is too far gone (bored out) a driveline shop can replace that yoke.

Sounds better. So how would I know if it’s too far gone? Will I see the grooves and teeth worn?

If a U Joint is bad, drive it about ten minutes and then put your hand next to it, if hot, its bad

If its anywhere near as bad as mine was, crawl under the Jeep, grab the rear drive shaft and try to rotate it (With the jeep in park, all wheels on the ground) If it clunks over or has any movement, the U-joint is bad.
