Just installed subframe spacers...now clunking?

[csdcowboy]

I put them in Sunday, and it made a bigger difference than I was expecting! Goodbye suspension gap! haha

But the problem...the rear end's been 'clunking' quite a bit, particularly when shifting. If I make it really smooth, I can usually eliminate most of it, but not all.

Also, I've noticed that when I go into reverse, it makes a grinding sort of noise. I haven't had the chance to look into it to see if it's a brake issue or transmission...or something else.

Anyways, is there something I could've done wrong w/the spacers? I put them in tapered side down, like the directions stated, tightening to 65lbs. I used the diffferential as the floor jack point, but I can't imagine that would be the problem. Is there anything that could've been hit or something that might result in the clunking?

Thanks for any info!
