Re: Shimmies
Do your shocks have any stroke left or is it greatly reduced? You could be bottoming out on the shocks, and this may induce shimmies.
Are you sitting on the bump stops? What is your alignment like? Check your rear end mounting bolts. Typically your trans should angle down at the same angle your rear end angles up. Home Depot or equivalent have a nice angle finder I have used before to set up rear ends with. |

Re: Shimmies
Driveline angles shouldn't be that far off when using a typical kit like Belltech.
First... Double check the fasteners are tightened correctly up front. 2nd.... Re-Check that your wheel bearings are correctly secured/tightened & there is no play. What were the alignment specs after lowering?
