Here's what was done:
A brand new set of FRPP 4.10's were added along with a brand new tracloc unit.
Speedo gear was not changed. Friction modifier was used. All new bearings, washers, shims, etc...
Prior set up was 3.55 gears with open rear end.
Here's the symptoms:
At speeds above 65 when you let off the gas just a fraction a vibration that sounds like "running over rumble strips" occurs. It does not happen below 65. The sound/vibration is definitely coming from under or the rear of the car. There's no clunking noises when put into or taken out of gear.
The guys at L&R Service took it apart and checked everything. The fluid's clean, doesn't smell burnt. Any ideas?
