Failure of front wheel hubs on 2000 Silverado 2500. Replaced both shortly after purchase of truck about 14 months ago. After about a year both are worn out again. One has extreme play. Completely stock truck. On road use only. About 5000 easy miles on the hubs. Seems that one is close to falling apart. The other is on the way. Because of the excess play braking is compromised as well as stability. Not sure what brand they are. But bought on ebay. cgi.ebay.com/ebaymotors/ws/ebayisapi.dll?viewitem&item=160322928700#ht_2306wt_1004 I can only imagine how many people have hubs falling apart well before normal wear and tear.

The contactreceived NHTSA recall 05V379000 concerning ABS. He took the vehicle to the dealership, and had the work performed. The ABS iwas still activating, therefore, the problem had not been corrected. He took the vehicle back to the dealership. The hub assembly was corroded and needed to be replaced. According to the manufacturer, the recall did not cover this, and it will have to be replaced at the contact's expense.

The consumer stated that 2000 Chevrolet Silverado was having a problem with the ABS engaging at low speeds, 5-10 mph. The consumer contacted GM, and this vehicle not included in the recall. The consumer took the truck to a repair shop and had the truck fixed. The repair shop replaced the hub bearing. The dealership was contacted, and they said that it happened a lot. The bearing was replaced on the left front, and that seemed to have fixed the vehicle.

Anti-lock brakes kick in when attempting to stop on dry pavement driving slow. When this occurs, the stopping distance is greater. The greater stopping distance increased the chance of hitting something. The dealer replaced the front, driver side hub assembly.

At low speeds the ABS system locked, and vehicle will not stop. The ABS motor popped and pushed the pedal back. This past Saturday couldn't get the vehicle to stop and hit another vehicle. Took vehicle to the dealer, and they replaced the front hubs sensor, but problem recurred.

2000 Chevy Silverado Z-71, 4WD, V-8 extended cab 31,000 miles. I purchased the vehicle used on June 24, 2004. In September, 2004 I noticed that the ABS brake system would activate as I slowed (< 10 mph) to a stop. This issue began intermittantly but worsened as I continued to drive the vehicle. By Jan, 2005, the ABS would activate every time I applied the brakes at slow speeds (< 10 mph). No trouble lights came on. I did not have any accidents with this issue but had one very close call in a parking lot. This incident caused M to investigate and fix the problem. In late January, I had a GM dealer investigate the issue and they recommended replacing the left front hub assembly. Given the high price the dealer was going to charge for the replacement part and the labor, I elected to purchase a replacement front hub assembly from a local auto parts store (autozone). I replaced the left front hub assembly per the vehicle's service manual directions. And the problem went away. The hub I removed was heavily corroded with signs that the seal on the inboard side of the hub was corroded with a portion of the excluder lips missing. I still have the hub assembly that was removed from the vehicle and would be glad to provide it for teardown inspection. In addition, I am a degreed mechanical engineer that works for a leading axle and driveshaft manufacturer and would be glad to discuss this serious safety issue further. I believe that seal failed and this allowed debris / corrosion to enter the hub assembly which then subsequently caused a signal interuption between the tone whee and speed sensor. Thus, the ABS system believed that the left front hub was not rotating and caused the ABS system to activate. My issue is very much like the issue described in the May 27, 2005 issue of the detroit free pess titled "GM truck owners insist brakes are a problem".

ABS brakes engage each time I come to a slow stop( I.e. pulling up to a stop sign or red light) extending my stopping distance. Dealer states that the ABS speed sensors and front hubs must be replaced but cannot tell me what is wrong. The ABS warning light does not come on although according to the dealer( kelly Chevrolet, butler, pa) the system is malfunctioning.

The antilock braking system began to pulsate when braking at 5 mph and as a result the vehicle did not stop. The front hubs were found to be the cause and were replaced.
