Over the summer, due to bad vibrations and shuddering, I replaced my driveshaft and CSB, which were both bad and had to go. Well, a new vibration has appeared. Not nearly as bad as the ones I was having before, but just as annoying, as far as problems go.
The vibrations I was having before were near the top of 1st and 2nd, at around 2500-3500 rpm, but they were VERY harsh, like shaking the car. The new one that's started up lately starts in 3rd at just over 2500-3500, and continues into 4th around the same rev range. I haven't had the chance (or open road) to see if it goes away after that range, but I think that it might. It also goes away if I lift off the gas a little.
My greatest fear is that it's still the driveshaft. The one I replaced my bad one with was a used one I got from Alex, with only 111k on it, as compared to my old one which had over 220k. But I was under the impression that driveshaft vabration only came in range of about 2-3k, in 1st and 2nd, which is where 99% of people complaing of DS vibration say they're getting it.
The Bentley manual says that one cause of vibration could be the final drive going bad (which I assume means the diff), which in my case very well could be, as my diff is getting loud and is getting close to giving up the ghost. I have a replacement for it, just haven't gotten around to changing it out. Should I replace that first, and see if maybe it cures the problem before I go investigating the driveshaft yet again?
