Hello anyone have any ideas at all on this? 92 S83P. 43thousand km. Drove it for 4 thousand km and it was fine. - I put a 2 inch lift on it made noises when you were driving 60 km hours. Sounded like front CVs. So - I dropped the front diff 2 inches with square tubing. The noises were not as bad. But at 60 km/h when you let off it made really bad noises the same. While the driveline was under load it was fine, driveline not under load noisey. So I am thinking U joints. - I replaced the back 2 even tho they seemed fine. Thought they could be dry no grease zerks. Noise was not as bad but still there after replacing the back. Was feaking terrible before. - I check the front driveline and notice the front driveline is being driven at all times and the diff locks up with vaccumm when 4 wd is engages. The front U joints were hooped both. The front pinion u joint was worse. I replaced both. And it is not as bad after but now from 80 km/hour or faster if I let off the gas it makes the same kind of bearing noise in 4th or 5th, but not all the time. Put my foot on the clutch and it goes away. -My fears are tranny, or differential bearings. What do you guys think???
