Details

If you want to keep your original drum brakes on your favorite truck, we have you covered. The original came with ball-type wheel bearings and if you can find them, they are very expensive. Upgrading to modern tapered bearings is the only way to go. Tapered bearings disperse heat better and can deal with today’s grooved roads and modern wheels and tires much better than the original ball type.

  • Kit 916-31952 includes two inner and two outer wheel bearings, race, and two seals.

Summary: Very good, price good. The only thing is to flatten out the seal a little as it rubbed on the backing plate on both sides. I have a Canadian model which may have been slightly different.

Yes, I recommend this product.

Summary: Was skeptical about changing bearings right before a 600 mile round trip to Endless summer cruisin, but had to replace the original ball bearings because cage was getting bad. New bearings worked flawless, would do it again. Only problem is the flange on the grease seal has to be flattened out so it doesn't rub backer plate on hub.

Yes, I recommend this product.
