well i just got an AA sye installed and tomwoods driveshaft for a 4.5 in lift and now i have a slight grinding in my rear, it sounds like its comin from my differential and i can really hear it around turns im not sure what it could be from. it wasnt happening before the lift or sye

It's your LSD. If you changed your gear oil, then you need to get a bottle of friction modifier and add it to the rear diff. It grinds because the gear oil doesn't have the proper lubricity to properly engage the clutches. It's clutch chatter. It will go away with the additive...... :lecture:

now whats LSD?...and would this have all started happening just because of the lift or different angle?

 

[jeepguy97]

I too believe it is in the LSD. If it only happens when it goes around turns it would seem to be the likely culprit. Why it happend with the lift install I don't know...

LSD=Limited Slip Differential
