Hello Blazer fans. This is my first post and I need some help. I have a 91 2wd s10 blazer and is lowered 5" front and rear.Tire size is 235/60/15. When accelerating a loud scrapping./clunking noise can be heard. What is this noise? I can find no scrap markson the undercarriage.I did find the tires were scrapping a little and this was when I had the rear lowered 6". I have since installed 2" lowering blocks instead of 3" blocks and the samesound isstill there.AmI risking major damage todrivetrain componentsif i contiue to drive. Please any help is greaful. Thank you.

Lowering components:
Front: 3" coil springs + 2" spindles
Rear: 3" leaf springs + 2" blocks
Nitro shocks

did you take out the bump stops? also did you put in smaller ones?

Yes, bump stops removed. Actually had toC-notch the rear frame to add clearance for the axle.
