Ust got done putting a 3" lift on my jeep. Now that I'm driving it I'm noticing a grinding noise/feeling right under me when I barely tap the gas or let off of it. Anyone know what it is? Plus some stupid mechanic told me to put the jack on the t case and it got bent in a little?

 

If you dented the tcase housing then chances are its grinding against the internals.

 

How could I fix it ?

 

Depending on the severity, new t-case, or just the cover.

 

Just the cover I'm guessing

 

Here's the dent idk If this will cause what I'm feeling

 

Looks like the case is just hitting the floorboard try taking the crossmember off and straightening it to see if that helps.

 

Alright thanks I.l try that

 

Or could it be your exhaust rattling on the rear leaf spring shackle like mine does on take off and let off?

 

Don't think it's that

 

My crossmember is dented to all hell. So
It's prolly not that. maybe it's bad driveshaft u joints and have the extra pinion angle just made it worse.

 

Good call. That totally slipped my mind. BRAIN FART (verb): An involuntary release of ignorance.

 

Actually I remember some mechanic told me my drive shaft was going bad. So how much would a new one be or how much u think to fix it

 

That cross member isn't dented enough to be causing t-case issues. More than likely it's the rear DS u-joints binding due to the angle. Get new u-joints and the vibes should away.

 

Alright is there a specific size I'd need?
