Q: My spider gears in the rear end keep busting. Chunk isn't harmed. What is the problem?

asked by on

My spider gears in the rear end keep busting. I've replaced them twice, and both times they've only lasted a month. Chunk isn't harmed. Why do they keep busting?

My car has 267789 miles.
My car has an automatic transmission.

Hello there, thanks for writing in. The spider gears are only used when you are turning left or right, unless you have two differently-sized tires on the same axle, in which then the spider gears will turn all the time.

If you have a limited slip rear end, then your clutches will eventually be worn out and may need repairing or replacing. Also, when your spider gears are not moving, they are applying power straight ahead, and if you overload the rear end by exceeding tow capacity, you may damage the spider gears.

They will most likely not fit without trimming the metal. I think you will not be able to go bigger than 32/1150 without trimming. It will also depend on the type of tread on the tires. Some of those knobby...
