I've got a 2000 Tahoe that makes an "erp" noise when I hit bumps sometimes at slow speeds, as well as when I start or release the brakes at a stop sign, etc. It sounds like it's only coming from the rear where I have drum brakes.
I got on the rear bumper and really kinda jumped up and down and gave the truck a good shake up and down and left and right and not a single noise resembling this "erp."
I did notice that if I put the brakes on and sit at the light and it's real quiet when I let off the brakes but before I gas it I hear the sound.
I don't really know how to describe the sound - it's almost like a very slight version of squeeling tires or something...and it's very quick, like half a second, but audible. Some of time it's louder than others.
Trying to avoid paying the dealership to "diagnose" it...so any help would be appreciated.
EDIT: I forgot to mention it has about 110k miles and seems to run well other than this. Just worried it could be a tranny problem.
Also, what else should I do to this truck that I just bought? I was thinking of changing the plugs, oil, tranny fluid, and maybe coolant. Any suggestions on spark plugs, gaps on the spark plugs, or types of fluid to use?
