Hello everyone, my 1970 280 sl, auto trans. (153k on trans and rear-end) has developed a vibration in the rear upon acceleration. It almost feels like the rear flex joint needs to be replaced. The transmission is shifting fine. It's most noticable accelerating from a stop and in the lower gear ranges. Once cruising not as noticable. Any suggestions to diagnose it properly?
I also want to change the rear diff. fluid. How do I determine if I have a limited slip diff.? The owner's manual suggests specific diff. fluid.
Thanks
