97 XJ 4.5" IRO Long arm kit, 33x12.50's.
This has been going on for a little while now....and it has offically pissed me off. Whenever I drive it and Im at a moderate speed (35-45 mph) I can feel this vibration and grinding when I pressed my left foot onto the floorboard, I can't really hear it, but I can almost hear it through my foot, ya know?
The front driveshaft is pulled - new IRO long arm kit (3 months old) exhaust has been redone from the headers back and tucked up nicely and not touching anything!

I took it up to a shop that I frequent and they have had it since 8 this morning and I get a phone call that he couldn't find where it was coming from but could feel it when driving....

Not sure...My first thought is an axle u joint....but I can't really tear into anything because my complex that I live in doesn't allow us to work on cars...

Any ideas?
 
any mud between the calipers... my xj had a weird vibration but i found out it was bc of the design of the caliper and the type of pads i was using... weird i know..
 
i would bust open front diff cover and check ya gears also while drive shaft is off see if any play in ya front yoke could be bad bearing number of things on our type jeeps vib especially lifted with big tires... good luck
 
my guess would be check ya u-joints in rear driveshaft and check for pinion bearing slop also make sure the wheels arent warped have had that before and it makes a hell of a vibration
