What is wrong with my 1997 Chevy Suburban?

[Alyssa]

I have 1997 Chevy Suburban 350
- We were driving down the highway; went up a hill and the truck downshifted. Now the engine squeals and rattles; in most cases the squeal/rattle is detectable, other cases it severe (sometimes I think it's going to seize), and in other cases it doesn't do it at all.

- I've taken off the drive belt and I know it is nothing that is belt driven. I've canceled all the cylinders and the noise still continues. I've thought that maybe it is the flywheel, but I'm not sure if that is the case.

What's wrong with my suburban?

Sounds like the torque converter or trans fluid pump is going out.

i would not vote for timing chain problem. this one i would have to see in order to figure out what was causing it.,

is the sound coming from the top end somewhere, or from underneath?

this is something ive never heard of nor seen happen to these vehicles and engines hmm.

sometimes the a/c compressors go bad and cause noise knocking or squealing but you said you removed the belt so hmmm

interesting.....

how many miles you got on this engine?


good luck

If it is still making noise when the belt is off, sounds like the engine is junk. Use some common sense and get it to a reputalbe shop and have it checked.
