![]() I recently noticed at about 75-90 I have serious vibration on deceleration. I replaced the u-joints and still does it. When I replaced the u-joints all 4 of my DS bolts were finger tight. I also noticed that I can twist my DS about 3/8 of an inch each way before the tires turn it may be more like 3/4 in. any info would be great

![]() The stock balancers are crap IMO, they have a rubber seal that comes out over time and will be visible if it is, this will throw everything off balance, put a nice balancer and an aluminum DS on and your vibs will go away. The stock DS's aren't balanced to well either. Good luck.
