Seal Failure Causes Major Automotive Headache

According to my experience, this product was a total waste of money. The National Oil Seal I purchased failed within a month, causing significant damage to my engine. The pros are that it is affordable, but the cons are that it's unreliable and not worth the risk. Do not purchase this product if you value the longevity of your engine.

Pros
  • Durable and long-lasting.
Cons
  • Potential quality issues during manufacturing or shipping.

Well made, fits well.

Proper hub seal on Ford 10.25 or 10.5 Sterling rear axle. Easy to use (I use a press) and a good fit. Provided it seals well. My spindles aren't perfect (a few minor blemishes), so this old truck will probably be a fair test of how strong this improved design is. This is a double lip seal (two lugs on the spindle, inside and outside) that looks like it might seal a little better than the old factory single lip.

Pros
  • Permanent test results
Cons
  • Newer model could have been selected

Well made, good fit.

Matching wheel hub seal on rear axle Ford 10.25 or 10.5 Sterling. Easy to use (I use a press) and a good fit. Provided it seals well. My spindles aren't perfect (a few minor blemishes), so this old truck will probably be a fair test of how strong this improved design is. This is a double lip seal (two lugs on the spindle, inside and outside) that looks like it might seal a little better than the old factory single lip.

Pros
  • Replacement parts
Cons
  • Unbelievable price
