4.10 8.8 Carrier Play

[aaronhahn777]

I have play in the rear differential carrier (8.8 4.10)? It is the small gear inline with the main cross pin and has about a millimeter of play.

Can you rebuild the carrier? Or should I just purchase a used one?

(so much for my brake job... hahha. started with that... then found a bearing leak... then I pulled the shafts to replace the seals. Then I found the loose gear... now that explains my highspeed vibration... sheesh At least automotive work is fun.

That gear should barely move unless you're doing one wheel peels. I'm afraid your vibration is likely something else.

You could jam an extra washer on either side of the spider gears that slide into the carrier to bring them closer to that gear. It'll be a pain getting it back together, but it'll.. erm.. take the slop out of them. Oh, you might need a hammer to get that top and bottom gear back in.


Otherwise, you will inevitably end up with a new carrier if you want all the play out of it. And then begins the fun process of carrier bearings, re-setting up gears, and all the time and costs therein.

Thanks for the tip. I've got a good buddy that owns a truck parts shop... so he hooked me up with a new 4.10 8.8 limited slip diff off an 07' fx4

Time to go wheelin'
