I bought a Delco AC bearing hub assembly for installation in my Cadillac DTS and paid a high price for it. Nice car, so why not go for the best for parts, right? This camp lasted 2 months. ONLY 2 MONTHS! I wish I could get a refund but who wants to spend 2 hours on the phone jumping from Amazon extension to Amazon extension? FYI: I'm a process engineer with 40 years of experience. I have built 4 complete cars and service my cars myself. Long story short I have the right tools and know how to replace the hub assembly. I've done that many times. Simply put, this part is garbage. UPDATE: I replaced this Delco AC hub assembly with one from Moog. Time will tell, but first impressions are a lot better than Delco. The bearing arrangement feels smoother and even the packaging is excellent. Before you buy a hub, you should at least think of Moog. I think you will be impressed.
