I have a 2002 GMC Sonoma, Single Cab, SLS, Stepside, 4.3L, 5 Speed, 2WD, with the ZQ8 Suspension Package. We have had this truck since we drove it off of the showroom floor in 2003. This truck has been great to us however I change all of the fluids more often then they should be changed. Now when I drive the truck if makes awful noises. Its fine when you accelerate but it just sounds awful when you let off of the gas or push the clutch in. I think it might be the rear end, my brother thinks it the transmission, and my dad thinks its the clutch. Anyone have any ideas? I have already pulled the rear diff cover off and the rear end looks like it might be bad. Also does anyone know how many splines this truck has on the rear axle? Any help is appreciated.

Coasting noise is usually rear end, tell by sound coming from rear. Most likely needs bearings, if gears not damaged.

Compression check sounds great. That eliminates questionable valves and other innards. Suggest you might check out your coils while your in the trouble shooting mode.

Hey, sick. My name is Zack and i currently own a 97 s-10.Dont know if this helps any but I also had a blinker issue twice. do to the flasher burning out. First time was 86,000 miles or so. Then the second one shortly again after the installing the new one. Why or how it happened twice i do not know. But my only way of fixing it was to install a heavy duty towing flasher. its been working ever since.and its much louder so i can always hear it.uhh as for the truck running hot, my truck is constanly being pushed, the a/c is always on and I know that i frequently stomp the pedal but it usually stays in the high hundred degree range or so. The only thing i could think of is check your air filter, or flush your raidiator out and refill it. Well thats i got...so good luck and hope i helped with your problems. Peace out

Hey winc, Zack here, the only thing i might suggest is to try to find out where the noise is coming from, or where it would most likly be coming from.if u cant find out where,, get the truck lifted into the air (if you can) and listen to the truck engage into its gears. acceleration and deceleration should be completly smooth being that its in the air. uhh, the only other thing i might suggest is check for an exhaust leak? I really couldnt help you unless i knew what it sounded like. Sorry bud. Good luck

Hey Zack, Winc here. I figured out that the pinion gear nut came loose. So my rear end was vibrating like crazy because the pinion gear was loose. However I am currently trying to figure out if what size rearend I have. I need to know if its a 7.5" 8" 8.5" or an 8.6". When I tried to order the parts from summitracing.com I can pick specs of the rearend and that is telling me that it's a 8.5". However that is the same size as the Silverado 4X4 and my sonoma is 2wd. Plus my brother says that my rearend is smaller that a 8.5". If anyone can help that would be appreciated.
