Not worth the hassle

As my tests showed, this oil seal is not worth the headache of installation .While it may be cheaper than other options the lack of quality is evident in its performance..

Pros
  • Pro: Cheaper than other options
Cons
  • Con: Poor quality and difficult installation

Leakage nightmare, avoid it now.

After I put it to the test in my automotive transmission, it became obvious that this product is not effective in preventing leaks. I had to replace it within a week of installation..

Pros
  • None
Cons
  • Doesn't prevent leaks.

Wrong part for Ford truck not Jeep T-Case

Intended to be a replacement gasket for the output shaft extension cone housing on the NP207 transfer case. I have an axle oil seal that fits various 1997-2004 Ford trucks. The part number on the sticker does not match the part number on the box. The part was mislabeled. The part received was not ordered.

Pros
  • Provides good low temperature performance
Cons
  • ---
