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!

GM has recently issued a service bulletin for Steering-Growl Type Noise Coming from Front of Vehicle; Technical Bulletin No.: 11-03-08-001 Date April 14, 2011
Here is the recently released bulletin; Im going today because of similar type condition, I have already had the front left replaced. Hope this helps. 2008 Impala SS
Bulletin No.: 11-03-08-001

Date: April 14, 2011

Subject: Growl Type Noise Coming from Front of Vehicle
Models:
2006-2011 Chevrolet Impala (Including Police Vehicles)

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.

Correction
Important
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. If the noise is eliminated, replace both front axle shaft nuts with GM P/N 10257766 and tighten to the specification indicated below. 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.

My 2007 Impala SS has 55,000 miles on it. Had it serviced today by a reputable local tire dealer. They told me that there is a good bit of 'play' and recommended that the front hub assembly be replaced on both sides. Is this normal? Anyone else had this issue. I have only driven the car less that 6,000 miles in the 18 months I have owned it. Thank you for any input.

On my 2007 Impala SS, there is air but no heat on the drivers side. Anyone else have this problem? Any help or suggestion is greatly appreciated.

I bought a 2017 Impala LT Fleet from Hertz with 49,000 miles. I bought four new Firestone tires and at 60 MPH there's a noise that makes a drone, humming noise. I can feel it in the gas pedal and steering wheel. Firestone checked the tires and no play on the tires. They think it's a bearing, transmission, front end alignment needs adjusted but the noise only makes it on the highway. Need help what it is because it's annoying driving on the highway.
