I just got a 98 LS.
I was inspecting the rear brakes and noticed that on the forward side of the axle there is a shallow cup mounted to the leaf spring and a large conical rubber bumpstop kinda thing above it mounted the frame. It looks like a spot for a spring, but none of my manuals or parts places have any springs there. My guess is that it was for aftermarket performance parts that aren't there anymore. It rides nice, but vibrates a little sometimes going 75mph.
Anybody know what's missing?
I can post pics in a few days if necessary...
Thanx!

 

pictures would be best =P

 

nope, thats the suspension stop, its supposed to be like that...

its what the axle hits when you pull a 5th wheel...

 

haha omg is that real ? thats insane

 

 

wow thats insane =X

 

That would be it.
Thanks.
Glad to know I'm not going nuts or goin' down the road missing major suspension components...

 

Lol coolasice thats probably all kinds of fun to try and stop. Hopefully it's flat where you live.

 

it's def not mine... I just found those pics online...
