The first spot to check is that the vehicle has been lifted close to the estimated range in the Old Man Emu Catalog and that the suspension record has been completed.
Secondly, a wheel alignment should have been performed to ensure that the steering geometry is correctly aligned.
If the problem still remains then further inspection will be needed:
- Are the bushes in good condition? Have they been replaced recently?
- Were all bolts torqued appropriately and in the right location (ie: on the ground if necessary)?
- Are the tires all even and have they been balanced?
- Did the problem exist before the customers suspension was installed?
