It's vibrating, not violent shake, not felt on steering wheel. But it's at high frequency. Not anything like suspension related shimmy I had at 45mph. CV Joint at differential?

I had such a vibration that began at 80 mph. It was a worn out CV joint at the differential input flange. The output flange is a light press fit onto the mainshaft splines. There should be no play at all. Is the nut loose? Is the flange loose on the splines? If the play originates at the output mainshaft, the transmission will have to be disassembled for repair. The flange can be tapped back on with a plastic hammer. Make sure the splines are lined up.

Well. It's not 30mm. It's 36. So, back to store. At least I have nice Hazet tool now :) Have few more questions to everybody. 1. I have vibration that doesn' seem to be wheel related. Some under load. 1a. I also have metallic sounded clunk on slow take off and when load/unload drivetrain by letting gas off. 2. I have 2 sets of wheels, vibration repeats with both sets. Around 75mph 3. I have overhauled suspension and bushings, everything was fine. 4. I have new motor mounts. By looking at tranny mounts - they look good but I didn' take it off yet. I thought it's driveshaft related. Now that I have driveshaft off I see that universal joint is good, central support bearing good. Rubber seem to be intact and bearing is good. Flex disc as new. I got new one so will replace it anyway. Now that I have a leak I decided to address those issues. It looks like shift selector seal leaking and output seal might be OK. But it's all soaked there and I'm going to replace output seal anyway. There is noticeable play in output flange. In ETK I see PN 1 http://realoem.com/bmw/showparts.do?model=DE53&mospid=47588&btnr=23_0220&hg= 23&fg=15 It seems that I can get flange out with a puller (just like were suggested). How do I put it back? There is special tool listed in bentley to press this on. How I can DIY? I would do same like I did with flage on motor by heating it in oven and just slipping over, but bentley tells to cover in oil. Wonder if that repair kit will address this play? Anybody have any knowledge on this? Also, what could be the issue for #1a? Car has 172k miles.

I use shake to describe the 10-13Hz tire vibration and buzz to describe the 50 Hz driveshaft vibration. There should be no play and no "hitch" in the center or rear joint. Check those first and make sure the driveshaft is perfect before spending the big bucks on a new or rebuilt 6 speed.

We may be in a similar situation. My 1997 M3 (with 197,000 miles) has been exhibiting this type symptom for the past 20,000 miles. Here's the MO: 2nd or 3rd gear mid-to-hard acceleration, slightly uphill (puts more stress on drivetrain) between about 2,000RPM and 3,500RPM. It's a shudder or vibration(40 or 50 Hertz) that isn't in the steering wheel. I think it's the drivetrain as I feel it most in the butt dyno. It's fore-and-back, not side-to-side. I have replaced Clutch, flex disc, transmission mounts, engine mounts, and many rubber bushings. The engine mounts seemed to help most, but did not cure it. Something still feels loose. My next target was going to be the drive shaft (center bearing CV joint). I haven't thought about the transmission, but you raise a good point. It's possible something is worn in the output. Now I'm wondering whether to attach tranny or driveshaft first; both are original.

I asked Dave Granquist, tech at Red Line, about the same thing back in 2004, and he said there's no problem with using "old" fluids either opened or unopened: "I wouldn't be concerned using product that has been on the shelf for a period of time either opened or unopened, the original performance hasn't been affected they are still safe to use."
