Stop plate Gap

Post by 13CapriceNC »

I ordered new complete front struts and new Stop plates for up top. Now I have a pretty good gap between the stop plate and the body of the car causing a clunk over large road deformities. Has anyone else had this problem? The struts are in correctly, the springs were pre loaded. I am at a loss for what it could be.

I don't know if it helps, but when I did mine, I seated the assembled assembly into the "pocket" so to speak, before attaching the knuckle. So basically, before dropping the car, the strut mount was nice and snug in the area where it was going to make its home.

I can't explain it any better... someone here either PM'd me a while back or posted in a thread; I believe it was s/c'd cav but can't remember.

Well, I think the new complete struts i have purchased in April have fail bushings. Does this look like what failed bushings do?

I can't speak to that, but I know this is a very popular topic over at the G8 board as well (the space between the chassis and the strut plate). Do you have the old mounts to compare to? I'll grab a pic of my engine bay when I get home to compare.

Did you buy pre-assembled strut/spring units? Or did you have the components and build them yourself?

I purchased pre-assembled front struts. If the bearings / bushings / strut mount is bad since installing in April, That is not a good thing lol.

did you use the OE rubber strut mounts ? if so they are pretty much junk , and have been since GTO , they are to soft and collapse quickly

i use whiteline urethane mounts , even the aftermarket rubber mounts do not hold up well

Do you remember if you pointed both your washers down? Thats the way GM wants it. I think Whiteline instructions are different. But thier washers might be different also.

Here is the TSB on the New Washers:

I am confused by what you mean of the washers being pointed down. Are you talking about the washers that sandwich the mount? If so, I bought these struts pre assembled and saw that the washers were orientated as to look like satellite dishes facing away from the mount. Is that the correct direction they should be?
