Subframe mounts and engine mounts

[mauro12]

Hello guys , I’m starting to plan to change both engine and subframe mounts. Mine are still ok but they look very old and I want to improve the handling of the car . Do you have any idea about how much a mechanic could charge for the labor to do this job? It seems to me that it is quite difficult especially for the subframe mounts. I heared that if you don’t do properly, the engine could raise too much and hit the bonnet . Thank you .

I just did the sub frame mounts about a month ago. With experience (which I had none) it would pretty straight forward. The second side I did quite quickly (hour or so). I was able to do it with the brake caliper in place, with the hose connected.  My point, is would really boil down to experience as to how long it took.

I used the taller mounts (much less expensive) and had no clearance issues.

The change of these, made a big difference in the "tightness" feeling of the front end.

Im sure the experts here will provide more info

I found this kit of subframe mounts , have you ever tried ? https://www.mbclassics.de/repkit-sub-frame-W108-113

I guess it is worth to do subframe and motor mounts at the same time right?

I am mechanically able, but I think is too much for me to replace alone subframe and motor mounts, I don’t have the right equipment . I want the job done by a specialist , but here when they see classic cars they charge you almost the double . I’m trying to understand how much a specialist could ask for this job.

I had the car up on a quick jack, then a floor jack to lower the sub frame, after disconnecting the front spring perch etc.

That is the Febi Bilstein kit that is usually used, vs the 1/2" shorter OEM Mercedes part that is ~$6xx.

There are some good threads on this procedure.

How long it took to do the entire process?

I recently replaced both and an experienced mechanic can certainly complete removal and replacement within a few hours of labor.  Having a proper car lift and hydraulic jacks makes the job much easier as you essentially need to drop the suspension enough to fit the subframe mounts into the body.

How much did it change after these new mounts ? I’m sure is almost to drive another car right? More stable and precise.

The first side is always easier so I start on the manifold side because of clearance issues. I've often had to use a come-along to pull the subframe into position. So what looks like a nice, easy, straight forward job, can end up being anything but easy or simple.

Difficult to change the subframe mounts and motor mounts all at the same time without a hoist and a transmission jack.

What is a resonable labour price for the replacement of the subframe mounts?
My doubts are that since I’m in the process to replace the shocks, I would like to check if the subframe needs replacement too.
