it is making a kathunk noise in the front and the rear drums are badly rusted.
Thanks for the email, I will check them out. How bad are your axles? The rear brake drums on your truck are about $70 on the Autozone website. Have you checked into the front end noise, It could be just U joints which is a cheap repair. If you have more serious internal problems with it you may just want to replace it.
What do you have for gears. I have a 91 Suburban 1/2 ton with 3.42's in it I'll be junking in the springtime. If you want the front axle you can have it for free. I'll cut it out before it goes.
