WASHINGTON - General Motors Corp. said Friday it was recalling about 313,000 passenger cars and crossover vehicles to fix a fluid leak that could lead to the driver losing control of the vehicle.
The recall involves 275,936 vehicles in the United States, including the 2005-2007 Cadillac CTS and STS sedans, 2005-2007 Cadillac SRX crossovers, and 2006-2007 Pontiac Solstice and the 2007 Saturn Sky convertibles. About 38,000 additional vehicles are under recall in Mexico, Canada, the Middle East and Asia, GM said.
GM said the seal on the rear axle pinion, which provides power to the wheels, does not meet all specifications and could leak fluid. GM spokeswoman Carolyn Markey said the leak could lead to the drivewheel jamming up and locking while the vehicle is being driven, possibly causing the driver to lose control.
On the right is the new design yoke and seal. On the left is the old style.
This is the repair as outlined by the newest TSB.
I suspect the recall will use these same parts. I also suspect it will be an inspect and replace type of recall.
It looks to me as though the issue is dirt getting trapped inside the seal lip causing premature failure.
They seem to be putting a great deal of emphasis on keeping the dirt away from the sealing surface on this improved design.
The rear pinion update is similar.
Unless you have gotten this done since December 17th you probably have the original design seal on the left.
The only real issue as far as the gears would be that if the installing tech doesn't torque the pinion nut properly it will overload the pinion bearings and ruin them. I guess if it was undertorqued it might cause some backlash issues and possibly damage the differential case and/or pinion gear.
The Service Manual has procedures the installer should follow.
This includes the use of med. strength loctite on the pinion nut to prevent it from backing off and loctite on the drive shaft bolts.
