Drive shaft u-joint in the middle of the two drive shaft "tubes" has
play in it.
I went under the car with my "second-opinion" mechanic (a BMW
specialist) and he showed me how he could turn the front drive shaft
tube and produce a small "klunk" as the rear shaft tube started to
turn. There is play in the "u-joint" thingie that connects the two
My primary mechanic (Mercedes specialist) says I can just replace the
joint in the middle, no problem.
My second-opinion mechanic says I need to drop the entire drive shaft,
send it in as a core trade-in, and purchase a re-manufactured shaft
unit that has been balanced ($400). He says if we just do the joint,
the shaft will be unbalanced, leading to more serious problems.
Flex-discs have been replaced, but there is a definite lurch when the
car shifts when not under engine load. When under higher rpms and
under load, the car shifts much better, much smoother.
Does anyone have experience with this? Feedback is appreciated.
