Drive Train Axles Bearings problem
2006 GMC Sierra V8 Four Wheel Drive Automatic 62000 miles
I only use the 4 wheel drive to launch my boat, about 6 time a year during the summer months. The axles are not submerged. At about 40,000 miles the service 4 WD lite on the dash came on. When that happened, I could not push the buttons and shift into 4 wheel drive. I had an extended warranty, so I took the truck to Boulevard GMC in Long Beach CA. They said GM had a repair bulletin about a loose or corroded electrical connector. They repaired it under warranty. This was 2-1/2 years ago. 2 months afer they repaired it, the light came on again, and I had the same problem of not being able to put the truck into 4 wheel drive. I called Boulevard GMC and they said they were booked up for 2 days. Since I was going to be using the truck in 2 days, I called Peninsula GMC and they took it in the same day and diagnosed the same problem as Boulevard GMC had repaired 2 months earlier. Since it was still under warranty, I had them go ahead and repair the same problem again. Today (June 27, 2010) the same problem has occured again, and the truck is no longer in warranty. I would like information on the location of the connector so I can take it apart and repair it myself. Surely I can do as good a job as the dealership.
