Hey everyone,

I just completed the Guldstrand Mod w/ the help of mo67cam (Thanks you Sean). After cleaning a spot in his garage we got started Sat late. We were able to put in Hotchkis 2" lowered 600lbs springs and the KYB shocks. Except for drilling the first hole to big (sorry Sean I couldn't help to mention it) everything went fine.

Here is a question guys. My passenger side sits great. The lip of the fender just covers the top of the tire (235r60 15's)but, on the driver's side it's about an inch higher. The fender is right at the top of the tire. Both springs are set in the pocket. Sean and I were thinking maybe the frame is bent. I though maybe measuring the frame on both side because it may be the Body that is crocked. Does anyone have any ideas?

Thanks again Sean,
and others,
Tony

Get this, GM thinks in spec. is something like +/- 1/2" at the bottom of the lower A-arm!!! How are your subframe bushings? Are they squashed ?

I mention the dig about spec's b/c I got in a heck of a row(sp?) years ago with a factory rep. after my pass. side sagged about 3/4". I could tell by looking at my dash top b/c it sloped tpwards the ditch going down the road, and it wasn't b/c of the road crown, either! Everytime I looked at it I got mad!

They ended up installing stock heavi-duty 396 A/C springs for free after they sold me the springs for if I remember right $20 or $30/pr. pdq67

How about trying one of David Pozzi's suggestions.

Jack the rear end of the car up using a piece of angle iron on your floor jack, pointing up, in the center of the differential. This takes the rear springs out of the ride height equation.

What bushings do you have in the car?

What is the distance from the ground to the center of the front A-arm bolts on each side?

Also try disconecting the front sway bar. Just remove one end link.
A twisted sway bar can cause trouble.
Verify weather it is the body or subframe that is off.

I did undo the sway bar and tied it up. No diff. Im going to go to someplace flat and measure underneath the lower A-frame pivot point, with the back of car jacked up at the differntial and with it down.

I let you guys know

Thumbs up

I think I figured it out. I jacked up the rearunder the diff. until both rear tires were up. I measured from the ground up to the center of the lower A frame bolt on both sides 8-1/4" for both. And under the frame in front of the A frame both sides was 11".

I looked around underneath and found that my body mounts are all rotting away. So, its letting my body drop on the one side!

Do you guys think this is the problem?

Tony

Hey Tony,

The body bushing would definetly cause this problem but I also wanted to mention that your core support mounts were rusted pretty bad also. If they were rusted enough to flex a bit it would add to the problem. I think first would be to replace the body bushings.
