Brother of The Benz, joel
If it was my 89 300E, and before the shake rattle and roll did any further damage, I would take her to my M/B Dealer for a front and rear suspension inspection and a quote to repair.
Wheither you have it repaired there is up to you; but at least it would have been inspected by someone who knew what was what!
