18+ months, 15000+ miles, still like new!

Driven it for over a year and a half, city, highway and even some off-road, and about 15,000 miles. Absolutely no problem.

Pros
  • Cool product
Cons
  • Ok for the most part, but...

Revainrating 4 out of 5

overpriced. I could get a motor with me.

I've changed my rating, although no seals were included it was a great kit if you just need to change the bearings. The factory pads worked in my application.

Pros
  • Lasting test results
Cons
  • Almost never

missing bearing spacers

No shims, otherwise complete set. This and the Yukon Gear set were side by side. Got this one because of the price, missed that the spacers weren't included. I may be expecting too much, but seals are included in almost every other rebuild/bearing kit. Return and replacement as a set including seals.

Pros
  • High marks for support and durability from testers
Cons
  • The list will be long.

Inspect bearings before use - bearing notch

I bought this kit to use pinion bearings as mounting bearings and found that one of the bearings had a pretty decent notch (pic). If I wasn't just using them for fitness testing I would definitely come back. Therefore, check bearings, cages, etc. upon receipt and before beginning a project.

Pros
  • Decent work
Cons
  • Gone
