My wheel bearings on the passenger front wheel are going bad. I hear a whop, whop, whop sound that gets faster when I speed up. At first I thought it was tire noise, but I got new tires and its still just as loud. I have a couple of questions.
I have a 2001 ZR2 4wd.
How difficult is it to change these? Im no mechanic, but I can change brake pads, rotors, alternator, stuff like that.
What causes wheel bearings to go bad?
What ill effects is this having on my Blazer by not changing them immediately?
And what could happen down the road if I dont fix it soon? worst case scenarios
Also on a different subject- does anyone have a long term fix for the squeaky hatch? I lube it up every now and then and it stays quiet for a couple of months. I was just wondering if anyone has solved this problem, because I know lots of people are plagued by it.

First:
This help link is not for your year, but pretty close to the same. Its easy enough to do just about any one with a few tools can do it.

Second:
It's a sealed bearing. How you drive can be the biggest killer of these. I have seen avg. drivers not have to replace these til they hit 180k. Agressive drivers have to do these about every 30k. Weekend drivers go and never need to change them.
Third:
If you let it go too long, your wheel could fall off. And if this happens on a curve or highway (OUCH) is all I can say.
Worst case, you total your Blazer
Hatch issues try Liquid Wrench Silicon lube [light blue can] (use the Liquid Wrench [Yellow can] Penitrating lube first then after about 1/2 hr to 1 hr then use the other). I did this to mine and have had no squeeks yet. Did the same on an Explorer that had the same issue and so far 1 yr and no squeeks. What happens is the protective coating for the hinges wears off. Then the pins in the hinges get rusted causing the noise. A general lube will be like a bandaid til you can get the rust from inside the hinges cleaned off. Same thing will happen with your Door Hinge Pins, get some rust build up on them and your doors will drive you nuts when you open and close them.
