Pinion Bearing failed, dealer rebuilding entire rear end!
Driving to work yesterday morning and heard what sounded like a right rear wheel bearing going and BAM!!! Driveshaft hit the pavement doing 45 mph. Removed the driveshaft and using the front wheels drove into a fire department to get the truck off a highly traveled road.
Just spoke to the dealer and the entire differential needs to be rebuilt. Yoke is being replaced but not the driveshaft? Ring & Pinion are toast. Not sure if they are replacing the entire carrier or rebuilding my original core? Axles are being reused, but new bearings & seals will be installed.
I bought this truck brand new from the dealer's lot in 2003. Never roasted the tires, or went off roading, basically babied the truck since new. Had planned on changing the front & rear end fluids for the first time this spring.
Truck is a 2003 Quad Cab 4x4 Hemi with 34,900 miles so it's covered under the basic 7/70,000 powertrain warranty. Mechanic said he's never seen such carnage. Rear wasn't leaking so looks as if I just had a bad pinion bearing. Good thing I wasn't doing 70 mph on the highway. Only recent activity the truck has seen was towing a '72 Chevelle SS 454 home from MA last month.
Has to be at least a $2,500 job. Asked to have the driveshaft balanced, dealer said if it vibrates after the rebuild they will order a new one?
Very strange to say the least! Anything specific I should ask them to replace or inspect?
