Strange Road Noise......

Holeshot · 04-08-2005, 09:47 PM

There is some odd road noise happening to my Blazer.

When driving straight, it's there all the time......if am turning right - it get's louder........if I'm turning left it goes away entirely.

At first I thought it was worn tires......I had Yokohama Geolander AT+2's on until recently. They vibrated and shook the truck badly.
I bought some new BF All Terrains day before yesterday to get rid of the problem.
It's still there though......not a bad as before but still present all the same.

As long as I am turning left the road noise goes away.

I've asked around and the general concensus seems to be the bearings.......what do you think?

If that is so - what am I looking at for a fix? Are the bearings and the hub one unit?

I'm only - so so - mechanically..........and I've certinally never done something like that before.......is this something a backyard mechanic can do without an incredible amount of difficulty?

Thanks for your replies.....

Bad right hub bearing,,, Replace them both for even wear...

does the noise get louder as you go slower or faster?

No.......it pretty much stays the same.....

Hub bearings eh?
Something I could do myself with no previous knowledge? Or something best left up to pros?

How much are the parts?

Here's a good write up on changing them.

the hub replacement is not very difficult but all the ones i have changed on cars and trucks the noise gets louder as you get rolling quicker

Holeshot · 04-24-2005, 02:11 AM

Picked up a used hub assembly out of a 02' Jimmy for $100 (canadian) and put it in.

No more noise.

Thanks for your help everyone.

For another 30-40 bux you could have gotten a new one. I'm glad your noise is gone, but using used bearings means that the one you got is not going to have a warranty and it's going to wear quick... JMO

No, GM wanted $489 for a new hub bearing. Six months warrenty on parts, one year on work (at $110 a hour!)

Local car parts wholesalers wanted $299 and that is with my 30% government employee discount. Six months on parts.

So a used one was well worth it.
The 02 Jimmy I pulled it out of had 41000 km on it.

rlith · 04-26-2005, 06:15 AM

Didn't realize you were in canada...

madme · 04-26-2005, 03:10 PM

that price sounds right for a GM oem replacement hub in canada

Blazin2000 · 05-13-2005, 03:38 PM

i have the same thing where the noise gets louder as i go faster and it gets quiet as i slow down...i need to replace the hubs?

the_dubster98 · 05-14-2005, 01:51 AM

yuppers.. they get really bad if you go over a bump and the truck "floats over the bump?

Vsandme · 05-14-2005, 04:00 PM

Heh same problem here, mine was alignement...alot of vibration, I had some over camber in the fd tire odly

SteveI · 05-16-2005, 12:49 PM

Just replaced both hubs on my Jimmy over the weekend. I really wasn't having any major noise issues and the old ones didn't really look that bad but I feel better knowing they're new!

rlith · 05-16-2005, 01:10 PM

Hope you torqued the center nut to the right specs!

I bought mine off Ebay from a guy that bought them for his 4x4 S-10 and then sold the truck. I only paid $103 each for them.

They were brand new in the Box GM parts.
