MOTORMAN 513121 Front or Rear ABS Wheel Hub Bearing Assembly Set for Cadillac Pontiac Montana Buick Chevy Impala Pair 2

I bought 2 of these for less than my cost from the parts store. They worked perfect.

Fit right on had no problems

Replaced both front bearing units when the front passenger went bad with this set.I didn't at the time use bearing grease or torque wrenches (that I now have). I urge anyone doing this themselves, please invest in a torque wrench set from Harbor Freight or something, and make sure you pack any exposed bearings (if the bearings aren't sealed - and are dry) and the spindle with the proper grease. It's important to install a hub assembly with lubrication, and to install all bolts on vehicle parts with the correct amount of tightness.After 12,000 miles, including a 2100 mile 34-hour marathon move that ended with 50 miles of steep up and down mountain driving, the bearings are still in good shape. I don't really expect them to last longer than 2 more years/35,000 total miles, because let's be honest you're buying one of the cheapest 2-for sets you can find.MOTORMAN did me right with this purchase and I can't complain, no horror stories, no problems.

Installed on a 2006 Lucerne.~ 15 Oct. 2020. The install is not complicated. The removal of the old/bad bearing assemblies WAS/can be very challenging. They didn't come loose/out easily. Unless you are very lucky you really need an air compressor and air hammer/air tools, I did use air tools. Having a lift would be nice also. I did not, so my access was limited/awkward. My total installation time, ( including tool round up, old bearing assembly removals, new installation, clean up and stowing tools away, test drive) was ~12 hours total for both bearing assembly replacements or ~6 hours each.If you are doing this yourself, the thought of having to pursue a warranty/guaraunteed replacement part is NOT something that would make youhappy or made whole. So i chose a moderate 1 year warrantied product.This was the first time i attempted this and i took a chance on these bearing assemblies. So far no regrets. I'll update otherwise.

4th update need new bearings. Probably 30,000 in.3rd Update I installed these myself, i am not a mechanic, and now these have been installed for about 16,000 miles and dont know how many months still going just fine.2nd update roughly 12,000 miles one stud broke off. The rotor cut into the studs, may have been my fault idk why it cut Into it.Update roughly 6,000 miles later still perfect, we will see.Okay so I decided to write a review because after reading the current reviews I started to think I made a bad purchase, i was wrong. I replaced both bearings, which was actually easier than I thought and my car rides so smooth now. The Auto part store was charging almost 100 dollars for one and that was there cheapest and these where under 100 for a pair. I would recommend these forsure. Only thing is I only put about 300miles on them so far so I cant speak on how long they will last. I dont know what happened with the people that wrote some of the bad reviews cause I have no issues and not only did it fix the problem I had, my car also rides 10x smoother than before.

Our eldest grandchild is in drivers training and Grandpa is trying to get our old 1998 Pontiac Grand Prix in good running order for his first car. When I stopped driving it several years ago the wheel bearings were beginning to go out. My husband is very handy but he also has a lot of projects going all at once. It was important while doing research that I found wheel hubs with bearing assemblies that were easy to install and did not have to be modified to fit. I ordered this set of replacement MOTORMAN 513121 Front ABS Wheel Hub and Bearing Set. It came with both the left and right front hubs. The 5 bolts on each hub have a protective coating to prevent rust. The seller has a complete list of compatible vehicles which takes all the guessing out my purchase. When my new parts arrived, I was very pleased on how they were packaged and to get two for the price I would normally pay for a single hub. My husband had both hubs replaced in record time and my old car is going to make our grandson a very happy young man! I am very pleased with my purchase.

After I bought a 2000 Buick Park Avenue I found out I need a wheel hubs both front. After replacing the wheel hubs all of a sudden I had the swing back and problems and squealing come to find out first after if the bolt shot out and flattened my other Tire found out that the Hub bolts were backing out of the new Hub on my right side. So replace those bolts and now no problems so far until now the left. Now I started getting squealing and a swaying motion again on the left side found out that one bolt is totally backed out and gone the other another one was loose. This is a major safety issue Motorman needs to take a look at what is causing the bolts to back out when they are torque down to specs this should not be happening.When the first one flat in my tire I am lucky I was only doing about 20 miles an hour when it happened I'm normally on the expressway or on a road that is 55 or more per hour. Because of what happened I was able to catch the left side before something drastic happened. But I still had to replace a tire for no reason except for the bolt shooting across and puncturing my tire and I'm a little leery about Mortarman parts right now.

Good price, easy install, but only lasted me about 1 year. They started quietly humming about a week ago, and are now extremely loud. I was hoping to get a couple years out of them. I might have to replace them with another product so I can get a few years out of wheel bearings.

Good products.
