My 2007 GMC Sierra was making a funny noise so I brought it into Cottman. They told me they wouldn't know what it was until they got in there to find out.
They determined that it was a transfer case and it needed to be rebuilt. $2,200 and they rebuilt transfer case. Driving home the same noise. Went back they said it's a separate issue and they're going to have to charge me another $400 for a pinion bearing.
Called me said it's not just the pinion bearing but also the ring and pinion. I'm done these people are not honest.
My truck is still not fixed. At no point was I told it was a separate issue until after they repaired the transfer case.
