Does anyone happen to have part number rear main shaft seal cant find on schematics. For 07 wolverine 450 4x4

 

You'll need to use two ratchet extensions braced against the frame of the ATV - to keep the yoke from spinning.
If you notice engine oil collecting in the open void area of the rear arm, it's probably the rear engine seal. Expect to see some rust inside the void.

Best to drain the engine oil just before you intend to replace the seal. Good luck getting the 18yr old seal out...
