Review & Installation Video

Review & Install Video

Everything needed to rebuild 8.8" rear end. When you're installing new gears in your Mustangs rear differential, it just makes sense to install new seals and bearings while the housing is apart. This is particularly true if your pony has more than 60,000 miles on it. It insures against the need for another costly teardown and rebuild.

Attention 2010 and newer Mustang Owners. Starting in 2010 Ford changed the inner rear gear pinion bearing in all 8.8" equipped Mustangs. Because of this you will require a new 8.8" rear gear pinion bearing (Ford part# 9L3Z-4630-A) for proper installation, please see drop down option above.

Application. This Motive Bearing Kit is designed for use in Mustangs that have an 8.8" rear end differential.

Whats the difference? What is the difference between this kit and the kit for 35 dollars?

ncstang06

  • This kit comes complete with everything you need for a full rebuild: bearings, shims, crush sleeve, etc... The $35 kit is a basic kit that is the same as the more expensive version, but there are no bearings included. We highly recommend getting the complete kit and replacing all your bearings and shims at the same time to prevent any costly problems down the road. It's better to replace them all at once, rather than having to tear the car apart again just for a bearing gone bad.

I am replacing the entire axle housing on my 14' GT. It appears this kit has everything I need for the housing swap. The original housing has damage. I need to confirm if this kit does actually have all the parts needed for the swap. (Besides gear oil) Thank you I already purchased new axles from you guys.

  • The Motive Rear End Installation and Bearing Kit - 8.8 in. (86-14 V8; 11-14 V6) comes with everything you need to replace your rear end. The only other part you'll need, since you have a 2014 Mustang GT, is going to be a Ford Rear Gear Pinion Bearing - 8.8in (10-14 V8; 11-14 V6), item # 52994, (http://www.americanmuscle.com/88-gear-assembly-2010.html). In 2010, Ford changed the rear inner gear pinion bearing.

    Even if you send the car to the shop to get it rebuild, you are much better off buying this kit then paying for parts. I was quoted a $900 installation + parts for redoing my rear gears. So I purchased the parts and lube here in American Muscle and only paid for labor which was only $360, so I ended up saving $275.

    Must Have

    bought these along with 3.73 gears for my 06 GT, if your installing new gears you NEEEEDD this kit. NEVER redo a rear end reusing the original bearings and bolts.I had ford do the install and if i bought the same bearings and bolts through them it woulda been $250 extra. trust me these are so worth it and assurance that NOTHING can go wrong if you do the install correctly

    did what it was supposed to...

    well, its a bearing kit- no frills to it i guess. I wish there had been a larger selection of new shims to use- there seemed to be only 2 sizes if i remember correctly, so you have to use a larger stack of shims, as opposed to a few thicker shims... not that it really makes a diference i guess. it also comes with a kick a$$ motive bearing sticker for your tool box... oh, and the directions for how to re seal the cover were wrong... My instructions are to take that gasket in your hand, and sling it into the front yard as hard as you can- then go get some good rtv and put a bead on the case... those gaskets are worthless...
