Whenever I go over a speed bump ohit a sudden object where my rear suspension needs to soak up a bump I get this click noise in the back of my truck. I don't know what it is. I checked everything out and nothing seems to be loose. Whats going on? Has anyone else had this problem? How do I fix it?

Either the little plastic spacer that is between the leafs fell out or is there a hitch in the reciever.

Bad shocks?

Look at your leaf springs, there are four holes where plastic/rubber pads are supposed to be that take away leaf spring smack. One or two are probably missing. 9 or 10 bucks at the dealer. I believe mine were $8.48.

Is it harsh enough to be the G80 locking diff????

Its not the differential I don't think. I don't have my reciever hitch in when it does it and I just put yellow Bilsteins on at about 80,000 miles and I'm at 104,000 right now.

most likly the spring then because my spacers fell out and it does the same thing. merchant Automotive has a fix i believe.

Whats merchant automotive?

Thanks guys! It was the rear little pads. I was missing 3/4 of 'em. Cost $5.40 a piece to replace at the local Chevy dealer. I feel better now.

I am going to have to look at this. Mine clicks/clanks when I jump up and down in the bed. I thought it was a shock. No sense in buying new plastic thingies if they are just going to disappear again though!

I picked up 4 short rubber bump stops (Energy Suspension) from my local auto parts store. these have a bolt and nut on them, they are not coming off. this is the fix i used
