Drive train, fuel, suspension, steering & brakes / Transmission Slotted Nut
« Last post by Leester on Today at 14:01:12 »Hello all, I recently installed instruments in my project car, 1970 280SL, standard transmission and took it for a quick drive. Speedo started bouncing. Uh oh. Read up numerous old posts with warnings about the slotted nut at the rear of transmission. Getting ready to send speedo out (it needs recalibration due to 3.27 rear new to this car) but I'm still concerned about the slotted nut.
Getting at the slotted nut will require a fair amount of disassembly underneath. It seems like if the slotted nut is loose, there will be play, forward and aft, at the centering cross. If that is true, it also seems like loosening the driveshaft sections would enable me to push and pull on the forward drive shaft section to feel the play.
Obviously I'm looking for a short cut and hoping someone can let me know if loosening the forward driveshaft from the rear, and pushing and pulling the forward section of the driveshaft against the rear of the transmission will identify play and therefore a loose slotted nut.
Many thanks in advance.
