Ok so.. I am having a problem with my driveshaft.. I think..? HALP.
Setup:
s52
getrag 260
3.73 medium case diff
325i driveshaft
new revshift flex disk
brand new CSB
Ok so, I was having a vibration problem coming from the area around the CSB at 25 to 30 mph.. after that it dissipates. The CSB was completely destroyed, as was the flex disk. So, I replaced the CSB and FD.. put it all back in the car. Drove the car, still had the same problem. So I said "fuck it, I'll just get a whole new driveshaft."
Called Portland Driveline.. had them ship me a rebuilt 325i driveshaft with the normal u-joints. Happy as a bird, put it back in the car... drove it.. WHAT THE FUCK, still vibrating at 25mph to 30mph. Feels like there is a midget under my floorboard banging through up through the middle of the car. It's not HAMMERING it or anything, but it is definitely noticeable and driving me mad..
What the hell should I do? The whole rear end is tighter than a little girl's tuna.. tried 2 different sets of balanced wheels, no different. It does not shake after 30mph but there is a slight vibration that can be felt in the steering wheel, not the shifter. Everything feels tight back there.. 2 brand new rear axles..
No grinding/stuttering.. no different if accelerating or decelerating.. not RPM based, happens strictly at about 25-30mph. Car was JUST aligned and it did not affect the problem at all.
