I admit I don't know much about differentials, and I'm chasing down a Driveline vibration. Was hoping someone more knowledgeable could watch the and tell me if this is where my problem is, or if this appears normal.
symptoms are growling on deceleration, almost like a lawn mower.
After the lift, I replaced All 4 U joints, but the driving was always kind of squirrely . So, I recently put on some M-A-F caster correction brackets, and while it was down I went ahead and put on new spindles, and had all three bearings and races in the front diff replaced along with a new JF drive flange (was on sale from Witts End). The result is much better drivability, but I get a severe driveline whine from the front at any speed over 40 and a growling vibration similar to a riding lawn mower on deceleration over about 50.
With the front drive shaft pulled, the vehicle drives beautifully and quiet. I took it to the shop who did the differential bearings for me, they drove it, and told me it was the drive shaft. Definitely not a problem with the differential, and since I supplied my own Timken bearings, there was no warranty of any kind... he wanted to sell me a part-time kit to fix the problem though. LMFAO!
since I'm running ome J Springs, and the @sleeoffroad website indicates drive shaft issues a definite possibility, I went ahead and ordered up a DC from Tattons. The new shaft has the same issue, maybe marginal improvement.
What I am noticing, is that the differential pinion flange is moving quite a bit. I don't know if this is normal or not. Thanks.
