Refurbish of Sub frame Assembly and Differential

Rear subframe Mercedes 280CE
Reading Time: 2 minutes

Restoring sub frames might be the next Transformer movie

After removing the whole rear sub frame assembly and all it’s components, they needed some love. Under is an example of all the parts (excluding drive shafts) of the sub frame. Have you never worked with these parts you might not have seen it fully before.

I had to remove some surface rust and then repaint all of the parts. It took a while!

Of course there will be new rubber mounts for the sub frame, both front at the mounting plates and at the differential hanger.

Differential got a nice cool color scheme, why not?

Also the subframe needed a good clean up of surface rust, I used a power tool (angle grinder) with a very stiff wire brush to get off the surface rust and old paint.

My hand were smoking due to the heat and hard vibrations when using the power tool, they were sore for a while after as well, tiring.
