A coil spring compressor can be purchased from some vendors for
about $520. +/- which is designed especially for use to recoil
MB coil springs; it is not adviseable to use anything but the
proper equipment in this situation. MB coil springs are very
tightly positioned, especially the fronts and, this is a highly
dangerous repair frequently misjudged in its attempted difficulty.
Fatalities have been recorded from inept DIY'ers and for this
very repair item. This would be one item to gladly hand over to a
professional. That specialty tool can best be handled by a more
expertly trained tech whose experience is worthy to be paid for.

In an aside, why would any MB springs necessarily need to be replaced anyway? MB springs rarely, if ever, require replacement.

Not trying to unduly scare anyone here; however, think clearly
and exceedingly carefully when looking to work on this suspension component. When or if in doubt on the coil springs, do seek guidance from a variety of qualified MB mechanics.
