dodge will not sell just the carrier bearing/mount separelty without buying a $1200 driveshaft. mercedes does however, we were unable to find a slk32 bearing/mount locally friday but after hours of looking thru the parts database and pulling parts up to compare we did find a clk setup that did fit for us. id recommend the slk part tho as the mounting tabs were slightly different on the clk but still usable if you can wait.

i woudl feel a thumping under the center counsil at the top of 1st gear due to the 2 piece driveshaft not spinning straight.

check the attached pictures, the mount casing is supposed to be a circle :0
