Pull to right on accel...return on decel...
 

1988 300CE, daily driver, 191k miles, struts and shocks replaced within past 2 years. I am experiencing a slight pull to the right on acceleration while at speed. Lift off the pedal and the car twitches back to straight.

Any suggested explanation would be appreciated; I like the insider info this forum can provide before going to a tech.

Sounds like an issue with one of the rear axle support links.

If you do a power brake & have someone watch the rear wheel, does it move in the wheel opening?
