....suggest having a qualified tech- - comprehensively review the chassis and suspension for 'worn' or 'excessive play' conditions- - often times older MBs need (upper/lower) control arm bushings (or the like)

...also at this time, you may wish to review the front calipers to ensure none are sticking/leaking

hope this helps

PS- do check the easy stuff like the tire swapping as well
