Chrysler Crossfire
Upgrading rear chassi


This is one information page of my collection of what I have repaired on my Crossfire.

Note:
You should not do any repair on your car if you don't have enough experience and knowledge! You use this information at your own risk! Don't blame me if something goes wrong.

If you have a Mercedes SLK R170 with a 320 engine it's almost exact the same.

Note:
You have to work with critical parts when doing work on suspension. Only do this if you have enough knowledge !

Chrysler Crossfire, rear bushings

2, Installation of new springs, bushings and rubber pads:

Now we have come to the winter season and I don't use the car much. It's time to install the new parts I have bought. To do this there are some tools needed and I don't have them. I asked my workshop if he could do this and that wasn't any problem. I handed over the car to him.

Rear springs:

The new springs installed, he had a lot of problem to do this because of rusted bolts, some broke and needed to be replaced. But after some struggle with this everything was done and it looks fantastic good.

I'm lucky that I didn't try to do this in my small garage.

At the same time he replaced the rear disc pads. I had already planned for this but forgot to tell him but he find it when he did an inspection of the rear chassi of the car.


Rear bushings:

The rubber bushings was the most important to replace. My old were worn out and even when they are new they are too soft for this car and cause bad road handling. With these new harder bushings I hope to get it better.

Look how bad the old bushing looked, it's crawling out on the right side.

The new bushings are divided in two parts and are easily to install, but to get out the old ones you must have a hydraulic press.


The old springs:

I had some difference in height between the car's left and right side. I was sure that one of the springs was broken or the rubber pads were bad. When checking the old replaced springs I can't see any wrong with them, strange. But it was good to replace them anyway because after 130'000 km they will broke sooner or later. It was very easy to do this now when the rear chassi were apart. Now the new will last another 15 years.


Old rubber pads:

Inspection of the old rubber pads which sits on top of the springs. Nothing wrong here either and they are of correct type, one notch or 5 mm.


Checking height:

Did this replacement of the springs change the height of the car ? 110 mm from the wheel to the fender on left side.

On the right side 100 mm, 10 mm difference. But the right front wheel stands over a pit on the floor where the water outlet is. I must find a flat floor and redo this measurement. It will be very exciting to do a test drive later and see if I can feel any difference. From the short drive from the workshop to home I at least didn't feel any disadvantage of the stiffer rubber bushings.

Later I will replace the lower rubber bushings at the front, they are very soft.
