Ok, '95 Mark w/ 109k. I purchased my Mark w/ 88k from an older friend. Then started getting a vibration, that drove me nuts - and have been working on it since.
Car has brand new Michellin's - with your foot off the gas it is like it is on glass.
I had it looked at by a driveline shop and J donated some of his time on a Saturday and took a look at the car with me (thanx again man!)
I swapped in a '93 shaft, which made no change. Had that driveshaft balanced and the U-joints replaced - very little change, almost none.
It would vibrate with my foot on the gas, whether it was flat groung, downhill, uphill - anytime.
So, I had it down for a month or two...replaced rear wheel bearings (and air bags and shocks while I was back there) - transmission mount and the tailshaft bushing (with the BOC forced lube mod kit).
I was pleasantly surprised to find approx 90% of the vibes gone. Which I attribute to the tailshaft bushing (the old one looked plenty worn). It is great on flat groud, going downhill, but I get an ever-so-slight vibe going uphill with an obvious load on the motor.
When J and I looked over the car, we found that the driverside motor mount was gone (original) - I have the SCP solid mounts in my garage, which I plan on installing.
So, on to my question: Should I expect the motor mounts to have a large impact on this vibration, or should I look into the Dynotech D-shaft from SCP, and sell my rebuild '93 unit?
Thoughts?
Thanx guys!
