i wanna know why i had to replace my rear end diff

i thought warranty only covers 3 year or 30000 miles

dont carry much for loads but when i relaced it the first time i just replaced the spider gearswith beefier gears from jawsgears.com

ok, i would check the carrier itself. if it is worn and the teeth mesh is off with the spiders, that will cause the failure. i always recommend using oem parts. aftermarket parts don't always mix well with old parts in the rear.

thank you i am curently replacing it with a rebuilt dealer rear diff. ill post back on how it turns out.
