Vibration Search Continues
I've been getting vibration on decelleration from about 75 untill 90 when it turns into a constant vibration untill I hit 105 plus at which point it goes away. I'm fairly sure it's a driveshaft vibration. I have 4.10's in there and before those went in I would get the same sort of vibration at 110 plus. The car is lowered and because it only happens on decelleration from 75-90 I figured the pinion angle might be the cuplrit but after getting adjustable lca's installed the problem persists. I have not gotten an adjustable panhard bar but I think my next move will be to get the driveshaft balanced. I was on the fence about it since it seemed like it'd be more likely to be a pinion angle issue as a result of lowering. Anyways becuase it happened before the new gears ever went in, and at one point I took it to a dealership who put in a new driveshaft (it made the vibration less severe yet still apparent) I'm hoping a driveshaft rebalance will solve my problem. Anyone have any thoughts?

RE: Vibration Search Continues
I mean decelleration, when I get anywhere between 75-90 and let off the gas I get the vibration. If I'm accelerating from 75-90 there is little to no vibration. Which is why I thought it might be the pinion angle, becuase under load it should snap it within spec I would imagine and then when not under load the angle would change and cause the vibration. At elast that's what I thought.
No I haven't removed any retaining clips. I assume those could potentially cause wheel vibration? The vibration I'm getting is definitely a drivetrain related issue. Thanks for the tip though.
