Loud bang noise when I turn sharp or hit a bump

I have a problem with my 93 Blazer 4x4. It makes a loud noise whenever I turn to sharp or hit a bump. I think it is coming from under the drivers seat but I'm not sure. I think the diff mount is broke but I tried pushing it up and it won't move. I'm pretty new with this 4x4 stuff (usually more of a street rod guy), just got it about 2 months ago. Any help is greatly appreciated.

Sounds like a t-bar mount to me. Those are prone to break on S10's.

I want to be a follower, but all the leaders seem to be lost.

its possible that the thumping sound may be due to a worn transmission and/or motor mount...might wanna check those...sometimes when they go loose it can make your drive shaft hit a cross member......

well thats what happened to mine...but i have a jeep so it might be different

I just fixed mine today it was doing the same thing, it took me about a month to figure out it was the torsion bar mounts pretty easy and cheap to fix.

Where on the torsion assembly did it break? Was it an obvious thing to see?

Just get under it and lift up on the rear of the bar and you will see the bracket that holds the crossmember to the frame is split, it is a bracket that is two peices of metal held together by rubber, kinda cheap deal but when you lift on it it will hit the frame and make the sound you hear when you go around a corner, you have to to a dealer to get the part, mine was $22. You will have to cut the top 3 threads off of it to get it to slide in and even then it will be a pain but it will go

Definetly the torsion bar mount, my S-10 has the same problem, but my Blazer
won't clunk even when wheelin' hard. I got mine from JCWhitney, but haven't had the plaesure of installing them yet. They seem to be a common problem.

My Blazer S10 used to make loud banging noises on turns or bumps. I simply had to replace the torsion bar mounts.

I got the noise fixed, it was the drivers side torsion bar mount. Fixed it myself for $18. Thanks for all the advice.

Re: Loud bang noise when I turn sharp or hit a bump

If one mount has gone out the other is getting weak. I replaced both when one broke. The drivers side is easy, but the passenger side is quite a bit harder. The passenger side torsion bar has to be removed. Take the tension off the bar by adjusting the bolt down and removing the "dog bone". Then you take a big hammer and starting knocking the daylites out of the bar. It will finaly move forward and fall out. then the mount is easy to R&R.
Good luck
