Has anyone else had any issues with the rear adjuster sleeve not being able to fully seat down in the spring pocket on the drivers side of the rear axle? On both my Camaro's i've had this issue. I had to use an oxyacetylene torch to clearance a brace that runs just under the spring perch. I'm not as willing to cut stuff up on my '91 and I may just have to cut down the adjust sleeve or notch it to let it fully seat and be level. Is this just something that people don't like to speak up about? What have others done to overcome this?

 

notch the adjuster if you have to. Or get a hole saw the same OD as the ID of the opening in the perch, use it to cut a groove in the brace, just enough to get the adjuster to fit. IIRC, the brace/gusset isnt flat correct?

 

does anyone have pics? I've been thinking of running them on my next project (with a moser 9", I wonder if that will cause additional problmes) and am wondering what I'm getting into with them.

 

Just notch the adjuster. I had to do this. It is not in a structural part of the adjuster. I have had no issues with this setup.

 

Look down hole where the bottom of the spring rests in the rear. Is half the hole covered? If so, you will have to notch the adjuster.

 

I'll find some time this week to trim the adjuster sleeve. I'll post pics so others have a clear idea of what I'm talking about.

 

I happen to have a spare 10-bolt & a spare set of GC Weight Jacks, so I went just went out & checked mine. Fit perfectly fine & flat.

The bottom of the WJ went in fully & sat flat 360 degrees around. Where is yours not sitting flat? What is preventing it from doing so?

 

On my 9 bolt, half the hole is covered about 3/4" down into the hole.

 

Hmmm...I have a 9-bolt in my car & don't recall any fitment issues.

 

And I have a 10 bolt both in my '85 and '91 and there's a semi longitudinal brace that covers half the hole just underneath it.

 

From the sound of things, it seems like some have it covered and some don't. I don't believe I took a picture of the obstruction.

 

if you take both out and look at the bottom you will notice they are different, one of the perches/sleeves has a grove that fits for the drivers side specifically.

 

Where? I'm not seeing a groove on either of mine. Mine are identical, top & bottom.

 

Mine don't.

 

Yours are cut down. They come much longer. Looks like maybe you did realize that the hole was blocked and cut down the adjuster to fit. See picture below. Mine were much longer as delivered from GC.

 

Ok so I had my car on the lift today and took some time to snap a few pics. the first pic shows the passenger side with the weight jack in place as it is designed. Notice how you can clearly see the bottom of the adjuster through the spring perch.




This second picture shows the drivers side of the axle with weight jack in place. Notice how this one sites about 3/4" high and will not rest on the spring perch.




You can see the obstruction in the following pictures.






Here's a look at the brace from the underside.

 

So how difficult is it to take a cut off wheel and modify the one side???

 

Yup, that is exactly what mine looked like. Just trim the adjuster and you will be good to go.

 

It isn't, it took all of 2 extra minutes to modify it to fit. Seeing as how that brace appears to be there to strengthen the panhard bar mount, I opted to trim the adjuster sleeve itself to avoid loosing any strength at the mount.



The point of this thread was to make others aware of this potential fitment issue. While it may not be a big deal to most, some don't have access to the proper tools to modify things accordigly. When I did my research before purchasing my Ground Control kit, this issue was never brought up.

 

Well, I just looked under my car with GCWJ & a 9-bolt. My adjuster on the drivers side adjuster sits MAYBE 1/8" up at most, from being flat. The passenger side does sit flat, exactly like yours does.

I had my car on a lift this morning but no camera, so I couldn't get a pic & didn't think to look either, But I got under the car when I got home to look.

I've had mine on for over a year now & I've never had a problem with it. The adjustable feature will take care of the height difference in how the springs set.

 

Yes but yours have already been cut. Look at the length difference in the pictures. It would sit at least 3/4" to high if it was un-cut.

 

That would be a 100% guess on your part. Neither one of us can see them, so neither one of us can say they are or aren't.

Whenever I pull them off, I'll compare them to my spare set. Which would be either that all 4 of my are cut, if they are the same length or something else.

What I do know is this....The ones in the OPs posts have a completely different adjustment collar on them than my spares do, so my spares are an older version. Quite possibly, the newer ones have taller "legs". My spares have a .83 leg on one & .86 on the other.

EDIT: Are they not made by Ground Control? They were sold to me, used, as Ground Control units. I've shown them to Ground Control before because they only sell in full sets now & I was trying to buy just a front set. They said I had to show proof that I had the rears, before they would sell me just a front set. So they saw the pic & said nothing like "Those aren't ours." But the ones on my car now ARE Ground control ones. Same collar, Ground Control printed on them. When I take them off for whatever reason, I'll check the bases & see if they are cut or even just one is cut.

 

Agreed its a guess. But your picture shows an uneven edge, leading me to believe they are cut. To your point, they have a different collar than both mine pictured above and the OP's. Also your threaded length seems to be much shorter than ours. Possibly an earlier version. Either way I can say with nearly 100% assurance that yours have a shorter collar than what GC is currently delivering. Just compare my photo to yours. This would explain why yours generally fits to within 1/8" and most others aren't even close without modification. Mine look indentical to the OP's.

 

You still missed the part that what is on my car, with only the 1/8" gap, most definitely are Ground Control ones. So how my spares looked turned out to be irrelevant.

Maybe what is on my car is cut? I dunno. I'm curious, but not curious enough to jack the car up & pull them out, just to look.

If & when they come off, I'll try to remember this thread & report back. I do wonder if one or both was cut. But if someone did cut it, it is still a hair, 1/8", "too tall".

 

Oh, the ones pictured are your spares, and not what is on your car???

If so, I sure did miss that point.

 

Yep.GCs on my car, dunno what brand those are unless they are an older version.

If anybody recognizes them, I'd love to hear what brand they are.

 

When i got my GC kit I had the exact same problem as well. All I did was dremel it down until it sat flat. No issues after 2 years of everyday abuse for me.

 

hmmm...... that is really strange, maybe GC sent you two right sides. When I got mine this past May, one of them had a notch for the drivers side already cut out.

 

Doesn't show that on their site, maybe they update the product?

 

Do you have any pictures? I've never seen any that had a notch.

 

Agreed. Hopefully they finally fixed the issue.

 

sorry guys I got no pics, I ll try and get some in the next few days.
