strange noise help on 420sel
 

recently bought an 86 420sel, 156k miles, noticing a strange noise on acceleration, speed is not a factor- sound is a metalic vibration/ kind of bell ringing deal, lasts a couple seconds and gone, coast- again accelerate- happens again. any ideas on what i should check first?
thanks, Tom :confused:

Center drive shaft support bearing. Put your hand on the hump between the floor boards in the rear as you hear it. It is felt distinctly in that area.

thanks i will look for it- is this a big deal to fix? am i flirting with disaster if i drive it as is for a while?

Clanging metal needs to be replaced without delay. I recommend not driving at highway speeds if it is the support bearing. Get it done this week.
