Hello everyone, I'm new to this site and i hope to get some input. My 79 300sd has been acting up. When starting up i noticed that when i shift to reverse the car steering wheel vibrates excessively. Once i shift to the DRIVE position the vibration is less and then goes away soon after.
This has been going on for about 3 weeks. This past week i noticed that when traveling at or above 25mph and turning the steering wheel to the right causes the steering wheel to clunk a bit...Im afraid its going to get worse...I have not checked the mounts or anything else. History: 5 weeks ago i was running very low on power steering fluid. Added the fluid and then i began to notice all of the above. Most likely its unrelated. I did use the Mbenz fluid. I just thought i would mention some history. Are the motor mounts hard to replace? Where should i start?

i would suspect motor mounts and possibly motor shocks too. they arent too hard to change. about three or four times as hard as changing a wheel and tire from spare to the car.
