Best house brand wheel assembly
I have used Moog in the past because all of the house brand assemblies have been cheaply built and had poor warranties. These TRO are well built and carry a limited lifetime. Hard to beat that. Prompt free shipping sealed it for me. I would give 5 stars if they were a bit more rugged ( like the Moog ), but would recommend them for OEM replacement with no reservation. Very happy.

I have a 2003 chevy blazer 4.3L with 4x4. These came within 3 days and were the perfect fit. All the parts stores around my area wanted over 100$ for ONE hub assembly. I always use 1AAuto for my parts. They were packaged very well and will continue to use 1AAuto for future products.

2004 chevy, wheel bearing hub assembly
It solved my problem.. I have heard a roaring sound for a long time, almost a year and it was getting worst. My brother kept telling me that it was the rear end needing greased, but it was not. The manager at Little BS in Medford wrote your name down and said I needed to order my parts from you. I am so glad I did. Thank you guys for getting my parts to me quick and very reasonably priced. I will order my next parts from you.

Satisfaction Survey
I was most pleased with the service to include price, shipping and instructions. I am most pleased with the results in that my vehicle is much quieter now. My only issue is with me! I am a 'senior citizen' and getting bolts loose on a 15 year old vehicle was a bit more challenging than I expected.
