I've been trying to track down a pulsating vibration that starts at about 70mph and worsens. Its unclear where its coming from. The vibration goes away if I shift the t-case into 4HI. Here's the jeep's specs:
95 XJ with 4.0
3.5 RE Super Ride lift
Advanced Adapters Slip Yoke Eliminator
Tom Woods rear driveshaft (recently checked for balance at a reputable shop)
Stock front driveshaft (recently rebuilt and balanced at a reputable shop)
Yukon 4.56 gears (installed at shop)
32 inch Mastercraft Courser MXT tires (balanced multiple times)
Details: (took place over a few years)
I first noticed the vibration after the gears were put in. The vibration would start at around 60mph. The vibration is a loud pulsating vibration that seems to come from everywhere under the jeep. I took it back to the shop and they didn't think it could be the gears. I then had the tires balanced and that didn't help. Took the front and rear driveshafts to be inspected and rebuilt/balanced as necessary. The front was rebuilt and balanced and the rear was already good. After install no change. I sent pictures of my rear driveshaft angle to Tom Woods and he thought the angles looked good. I left it alone for a while and ended up moving across the country. Some time later I took it to a local 4x4 shop and they noticed that the transfer case rear output yoke was a bit loose, so I inspected the yoke splines for damage (all good) and torqued it and the front yoke with my impact wrench. This did have an effect and the vibration now starts at about 70mph. I took it to a reputable transmission shop and they put it on a lift and got it up to speed in the air and tried to listen for anything. However, in the air the jeep would not make the vibration. The shop couldn't identify anything wrong with the tranny or t-case. I'm at a loss for what could be causing this. Does anyone have any ideas? Thanks.
