I have own my car for 6 years now, the last years I have noticed that the rear side of the car is a bit lower, it differ 8 mm. I have just thought, okay that is because the spring's stiffness just differ a bit because they are old now. I had planned to replace the springs even if I couldn't see that there were any wrong with them. Then I came across something where they talked about spring pad shims. I already long time ago bought two new spring pads to have as a spare for future fix. I didn't understand that there were different thickness of them. The two new ones I have bought is of the 2 **** model and 9 mm thick. I looked at old photos I have took of the car's rear springs but can not see which there are installed at the car.

Anyone here who know what the original thickness or how many ***** they have as standard on the Crossfire ?

Have a look here were I examine the rear springs, at bottom the new spring pad and some links with information.

I'm very glad that I at last found this and now know how to fix it.

The spring could be broken.

 

Hi,
I don't think the spring is broken, if it had been broken that side had been much lower. And when I inspect the spring I can't see that it's any wrong with it. Maybe a spring had been broken earlier and they only replaced that spring, not both.

Now I will order two new springs and two spring pad shims of 5 mm. I also order a set of front camber bolts.

The original spring pad on my Limited is A210 325 01 84 on the rear, which is 5mm. The coil diameter of the springs on the rear and the front are different. The springs are smaller in overall diameter and shorter in the rear than the front. Part numbers with 321 are for the front and 325 are for the rear. The difference in thickness of the pads are indicated by the 01=5mm, 02 =9mm, 03 =13mm, 04 =17mm. To raise the rear of the car you will need a thicker pad. Getting new springs is a good idea.

If the original pad shims is only 5 mm I get a problem, I want to lower the car. Maybe in my case I have a 9 mm pad shim on left side and a 5 mm pad shim on the right side. When I get my new endoscope I maybe can see the number of ***** they have so I can plan better what spare parts to buy. I read about someone that used a 1 mm pad shims, maybe he had cut a 5 mm pad shim down.

Have a look here, the 4th photo. I measure from the center of the axis to the fender, not from ground, then the size of the wheel and tire doesn't matter. Someone who have that height from a standard car ? I have 393 mm on left side and 382 mm on right side. As you see I have a lot of air above the tire, it looks more like a tractor.

Thanks for the PDF instruction, very good !

ps.
When I look at part number for the rear springs, both standard Crossfire and SRT hase the same springs, I thought the SRT had much more stiffer springers.

I looked at part numbers for the rear springs. The online Mercedes numbers are the same for the AMG 32 SLK and the 320 SLK; Also when I looked at the numbers in the Chrysler catalog
again the part numbers are indeed the same for the rear of the SRT6 and the Limited. The front springs have different part numbers, but the rear on all four cars are the same part numbers.
Hope that helps!

PS. I just looked at the pictures on your website; Perhaps you should disconnect the sway bar link and drive the car a few kilometers with out the sway bar attached and then remeasure the height left to right. Also there is a specific way that the spring fits into the lower control arm. With all the sand in there perhaps one spring has shifted out of position. I believe changing the springs with a new set is the best way to go at this problem. Removing the plastic cover on the lower control arm will give you a better view; just a couple small screws and pop it off. Good luck

 

Makes sense to me but then again, I never had an SRT-6. The rears are about the same weight. It is the front that is different because of the heavier engine (for the most part).

FWIW, when I pulled all of the suspension out of the 2005 SRT6 parts car I had, and went to move it to my limited, I found that the pad thicknesses were all different between the SRT6 and my 04 coupe. I remember looking at them and thinking that one end of the car was thicker on the SRT6 (front, I think) than the limited, and the rear end was the other way around. I wound up using all of the SRT6 stuff, and when it was done, the front end of the car sat very high, probably owing to the weight difference between the limited and the SRT6. Now that I have the V8, it sits lower than the SRT6 we have does, so that seems to confirm that.

Unsure why the parts catalogs show the same part number. When you have both sets of springs next to each other, it is immediately obvious that they are not the same.

 

Hi,
Thanks for the information that the rear springs are the same. To next winter I will take apart all the rear axels devices and see if I can better understand wha'ts wrong with it. 10 mm is just a fine adjustment but still I want it to be perfect.

Nemiro, you wrote that you have a V8 in your car. Is the Mercedes 500 or something else ? Any homepage where I can read about it ?

Now we have got winter here in Sweden and it's time to do some repair of the car. I handed over the car to my workshop who has the needed tools. Later when I check the replaced springs and rubber pads I can't see anything wrong with them. The rubber pads has the one notch. But the most important was to replace the lower rubber bushings which didn't look nice. At the same time replace the spring and pads was almost no extra cost for me.

I took some photos and wrote text to them to explain what was done:

In the spring I will do the same to the front.

Thanks a lot for all information you all have given me.

Astrofriend I hope you are successful in correcting for your 5mm difference. I have no experience with what you are trying to achieve but had some thoughts about the basic condition of the frame structure. It seems to me there must be a reference point or datum used for mounting the suspension system. If there is and are reasonablly accessable they can be used to determine if the mounting points are equal locationwise. This would help to establish if the frame structure has been twisted or distorted in some way. This could be why you need to shim. Just a guess.

 

I have a M113K from a 2003 CL55 AMG. Here is the thread about it.

 

The original inner lower control arm bushings are very soft. I do not know why those bushings were so very soft from the factory, but replacing them with the yellow polyurethane makes a lot of sense. IS the height difference left to right on the rear of your car corrected? What do you think was causing that difference and which coil spring pad did you use, 5 or 9 mm?

 

Hi,
The car has been smashed in the front, no traces of that today, but ofcourse it can be related to that. It looks to be half the difference compare to before I changed the springs, pads and bushings. One bushing was very bad, so I think it was that which cause the difference partly. But I must take out the car and park it on flat surface and redo the measurement. I just waiting for the snow melt away. One more thing, I can see that they have tried to adjust the toein/out at the rear with the defect bushing, now I can do a new adjustment.

The spring pad was 5 mm from the beginning which I didn't know before it was taken apart, the new pads are also 5 mm. So that's correct.

The new yellow bushings looks to fit perfect, much stiffer compare to the old standard rubber bushings, Anyone else who has these bushings installed ?

I know the lower front bushings are very soft too, I change them later and also the springs and pads if I can find them. Anyone know the part number of the front spring pads ?

Lars

 

Lars, read again post #4 The front 5mm pad should be A210 321 01 84.
When you check the toe adjustment check the thrust angle. It should be easy enough with laser adjustment at a good shop. That will let you know if the car is straight after the front smash damage was corrected.

 

Yes I know about thread no 4 but was not sure about the thickness in the front. Thanks, now I know which to order, 5 mm and got the part number too.

Lars

 

From the factory my Limited had a 13 mm pad on the front left ( A210 321 03 84 ) . I corner weighted my car and replaced that OEM 13mm pad with a 5mm pad to shift weight left to right up front and also increase weight on the rear of the car. I have no idea if every car from the factory has the same pad thickness.

 

I read in the service manual that's the way to level the car if it has differrent height on left/right side.

Look here:
https://issuu.com/heydownloads/docs/...re__complete_s

Page 32-33. So maybe very normal, and when I talk to my workshop he says that's how we do. Now I hope that it's possible to compress the spring enough to replace the rubber pad which sit on top of the spring without taken everything apart agian. I replace the 5 mm pad with a 9 mm which I already have (I think the 13 mm will be too much). The spring sits less than halfway out on the arm so that extra 4 mm will be about 10 mm at the wheel. The doors, windows, fenders and hood all sit perfect with no indication to be out of place.

So what left to do now:
Replace the 5 mm pad with a 9 mm pad on rear right side to get the car in level, bad that I didn't do that when the rear chassi was apart already.
Replace the lower front rubber bushings with some of higher quality. They are very bad today. At the same time I replace the springs and pad shims too.
After this I can adjust the rear and front toe-in and check the camber and caster. I have already check them with my DIY instrument, only the toe-in front is totally out of adjustment because of the lower front bushings is bad.
