rear end slipping on take off.
Has anyone else had any luck with the dealer solving the rear end slippage issue?
I have a 04 4x4 lariat screw with the 373 limited slip rear end. I took it to the dealer the other day and had them look into this issue and had my first oil change. When I picked it up the service writer explained that this is not a new problem. They experienced the same problem with 03 trucks as well. They put some anti friction lube in the rear end and lubricated the yoke in the driveshaft.
This has not solved the problem, and has created a bigger problem. The rear end still slips some time when pulling from a stop. But now the drivetrain in in a bind. This is noticiable on the highway. At 70 mph the truck was at 1800 rpms, now to maintain this speed I have to run at 2000 rpms. The other issue is when the truck is in 4h the front end clicks loudly and the vibration from the front end can be felt in the steering wheel.
Its back at the dealer today, I'll post the outcome.
I know ford will solve this issue, and there will always be a blue oval in the driveway.
