I maintain a fleet of impalas for my work, we have several 06/07 models, two of which have front hub bearings going out. Is there by chance a bulletin or recall regarding this?

No recall as far as I know but I had to have one of mine replaced at 40,000 miles due to excessive play/wear.

But then again there may be a service bulletin given the fact that my dealership was so quick to replace it :confused:.

No worries, bulletins only inform of the problem, they do not pay for it. Only a recall actually covers costs, but they only do recalls when they have to. Thanks for the input, I'll call the dealer to double check. I wanted to check here first since I can't trust dealers to tell me.

Sry to bring this up again but I was told by my friend that the Hub bearings are covered under the 100,000 mile warranty. He just had his replaced on his SS for free. Hope this helps someone out in the future!

Condition

Some customers may comment on a growl type noise coming from the front of the vehicle at speeds between 32 and 80 km/h (20 and 50 mph).

Cause

This condition may be caused by loss of preload on the front wheel bearings.

DO NOT replace the front wheel bearing and hub for this condition.

To diagnose the noise, retorque the existing front axle shaft nut to 220 Nm (162 lb ft) and test drive the vehicle.

On vehicles equipped with the police package (RPOs 9C1 or 9C3), add an additional Nord-Lock washer, GM P/N 20861489 between the hub and nut as shown in the illustration below.

I may do this on my 09 just for the heck of it. I can't tell you how hubs I had to replace on my 03 Monte Carlo when I had it. Ug.
