Drive shaft bearing for sure. I've never done a replacement of one, but it seems straight forward. Actually, the noise could beI better described as a rumbling, but only on acceleration and even then I figured out how to prevent the noise from occurring if I slowly accelerate and once the car shifts into second gear (usually about 5 seconds) then I'm good to go. Anything else I need to change while I'm there? I did front flex disc 2 years ago and its still in great shape (Uro Part), haven't done the rear, but I didn't see any signs of cracking when I last checked about a week ago...however I do have a spare rear disc just in case. all my exhaust hangers are only 2 months old and I added extra support with nylon zip ties, fuel filter was done earlier this month and those rubber hangers were replaced and reinforced with zip ties as well. Transmission mount was replaced 2 years ago, shifter bushing was replaced and tightened up with nylon zip tie last month (yes, I love zip ties they are easy to use, durable, end great for reinforcing those tedious jobs that are a pain to do and they last forever)...I can't think of anything else that might be in that vicinity. Please advise.
