New here & appreciate anyone's input. Just purchased this C70 & pretty handy with minor stuff & usually can find the problem but I'm stuck. when I put the car in drive engine running, I get this odd vibration / pulsation in the passenger front. put it in Neutral it goes away. While sitting if I turn the wheel all the way one way or the other it starts again. Also does this upon acceleration for just a short time & sometimes while turning. Drives nice otherwise. Tried to locate it to no avail, sounds like it's coming from left side of the engine.
Thanks for any input.

 

I'd look at the motor mounts.

 

Thanks , never thought of those & after you mention it I found some threads. Sounds like a pretty common issue. This could be exactly why I had no idea what it would be.
My thought was driveline or bearings but it seem to do it on Acceleration 5 to 10 mph then goes away ? Sometimes in a standstill in drive. Vibrations ?

 

wheel bearings typically moan and cv joints make their most noise at full turn. Bearings can also change sound with hard left or right turns (outside wheel gets more weight) but would not be dependent on power on/off. Brakes can make noise too - ie loose or damaged dust shield etc. To check motor mounts/torque rods try this - open the hood and have a partner put the car in gear with full brake. apply small amounts of power and look for any lifting or rocking of the engine. - don't do inside a garage or stand in front of the car in case your partner's foot slips off the brake :-)
