    • The Ford Performance 8.8 in. Rear Axle Bearing & Seal Kit will not fit on the 2010 Mustang V6. The 2005-2010 Mustang V6 Models were equipped with a 7.5" rear end not the 8.8. This part here is designed to work with the 8.8" rear end.

      Stop The Noise - Ford Racing Bearing Kit

      This FORD Racing Bearing Kit (M1225-B1) has the parts you need to quiet down those old / tired axle bearings. kit includes bearings and seals. My 2007 Mustang GT has 157K and I've changed the differential fluid every 40K with Mobil 1 75W140 Synthetic gear oil and Ford Friction Modifier (XL-3), but they still wore out. Use care when installing the seals to prevent damage. Thanks again American Muscle for the fast delivery!

      Can't go wrong with Ford parts

      My seals were leaking so i decided to change the bearing also. I also change to a Ford racing dif cover at the same time. Other than you'll need some special tools to remove and install the bearing, it was extremely easy and fast. Once the axles were out, it took less than 10 minutes to replace both bearing and seals.

      No more knocking sound when breaking. These will be good for the long run. Would recommend these when upgrading your gears.

      Great Bearings, Amazing AM Service

      Bought these after some chatting online with an AM representative about some groaning noises. I work at a Ford dealer and had a tech install them. After a fluid refill I was back on the road, with no noises. A great buy for noisy or leaky axles! As always, I appreciate the staff at American Muscle for getting my pony back on the road.

      Noisy rear end !

      Having some growling coming from the rear end of my 2014 Mustang GT yanked out the old bearings ( and I mean yank, they were stuck in there) Got the Ford Racing Bearing and seal kit from American Muscle. Shipped super fast (as usual) and installation was a dream compared to taking them out. Cruising in silence !!

      if your building your rear axle buy them

      the last thing you want is to spend all kinds of money making your rear axle stronger, and then have an issue down the road with the bearings. if anything, install them for the piece of mind.
