pinion Master install kit

[Sennin]

Hi Guys.

I need the pinion install kit for my front and rear diff (re gearing from 4.1 to 4.56). The Hummer already is at the diff shop for the swop out, but they cant source the correct bearings and seals etc for the pinion :gaah:

will these two kits work:

Front diff pinion:

Rear diff pinion:

I believe 09+ rear 8.6" diffs use a special larger pinion bearing than all others.

Ok thanks. So now the question is how do I make sure I get the correct kit for my setup [emoji85]

They are out there. The 09+ rear ends do have a slightly larger pinion gear. the fronts should be the same across all years though.

Here is a link on rock auto to master rebuilds

Here is the master overhaul from yukon for the front

And the rear here, this should be the correct kit for the 09+ kit with the larger pinion.

Yukon's website makes it easy to search by axle and make, and should point you in the right direction of the correct one.

I know since you're in SA it might be difficult to get everything in a timely manner. Hope this helps.

Thanks guys.

I got in contact with Chris from Drivetrain Parts in Las vegas and he threw me a care package together. If all goes well It should be here by Friday

Just to close of this. Got the parts. And had it installed along with my new 4.56 ratio gears. And I should have done it years ago. Totally different beast
