When I went to have my car aligned about 2 weeks ago, I found out I have a front wheel bearing going bad. Other issues I discovered have kept me busy until this point, but now I'm on to the wheel bearing. I ordered a replacement spindle lock nut from a local ford dealer (it's a one time use nut). Now I need to buy/order a wheel hub/bearing assembly. Are the units from the auto parts stores any good? The reason is that ford wants $150 for their assembly, but they're only ~$70 from any autoparts store. Anyone with experience with this issue?
