I have a 99 jeep Cherokee with a 6 inch lift...and i have been having this popping clunking noise coming from the front almost seems like right under the floor... It happens when I brake and when I hit bumps... Anyone else have this problem?

 

What shape is your trans mount in? Anything loose in the exhaust?

 

See that's what I was going to check tomorrow.. That's where I think the sounds coming from... What should I look for?

 

see if you can move the t-case up, you'll be able to see a bad tranny mount if theres any play in it.

Also make sure the control arms are tight on the body end, they clunk around when loose

 

A popping or clunking noise is either due to a loose or worn out part allowing extra play, or something is binding. Are all bushings, TRE's, and U joints in good shape? Do you have an adjustable track bar?

 

Yea all those are okay... I checked the control arms too and there not lose at all?

 

No adjustable track bar

 

If its a bad tranny mount is that a hard fix?

 

Did you get a fixed one that is a proper length for your lift or did you get a relocation bracket? Because that is probably going to cause the geometry to be off, causing a potential binding issue...

 

See I didn't do the lift.. But I'm pretty sure it's the right length.. Idk tho I could be wrong

 

Tranny mounts are easy, drop the crossmember and use an 18mm 6 point to get the two bolts out from the tranny housing. I had to use a 3 foot breaker bar on mine. Make sure you don't strip the bolt.

 

So after I take the crossmember off and the tranny mount just tightin everything up then?

 

Check the trackbar bolt, I had creaking sounds when I would turn the wheel and hit bumbs and my track bar bolt was loose.

 

Have you checked your ball joints?

 

The control arm mounts may not look loose to the hand, have someone put it in reverse and tap on and off the brakes so the jeep move a few inches at a time abruptly. Look at the LCAs.

Also have someone rock the steering wheel back and forth (semi violently) while you look at the front steering.
