I have a 2003 Blazer. My Lt. Ft. wheel bearing has been replaced 2x and now my RT. Ft. is going out. My question is; Are failing wheel bearings a routine problem with Blazers and are they eaisly replaced by the home mechanic?

There should be a writeup on the replacement procedure in the DIY section. It really isn't all that difficult, but does require some special tools to complete the job.

Failing bearings are not typical, but poor quality replacements are.

I agree with swartlkk, also on a side note they are easy to do as a driveway mechanic, one thing to make sure is that you clean out all the old grease were the wheel bearing goes and pack the new ones really well before installation.

gr8, that would apply to a spindle w/ hub arrangement, but the newer trucks have a completely sealed bearing, 2wd & 4wd alike. The 2wd bearing just doesn't have a driveshaft poking through it nor does it have splines for the driveshaft.

Yes, imagine my surprise when I pulled a front tire to check my bearings and found that sealed hub. When I asked my mechanic about it he said if they had to come off and be redone it would run around $300.

I have not seen a reacurring problem with wheel bearings on Blazers. I agree you need to replace them with quality hub assemblies. They do not have to be OEM parts but make sure they are made from good iron.

Find the self help thread.
TIMKIN is the bearings I recommend. They are not cheap, and for good reason.

Do you have your t-bars cranked, if so that will lead to premature bearing failures.

I just realized that after I looked at mine, dang sealed bearing. I am switching to a spline spindle anyways cause they don't make a drop spindle for the sealed bearing setup like your talking about!!
