At 3,300 RPMs while accelerating with some force during 1st and 2nd gear, my '98 318ti vibrates. I hear it, feel it around the cab, even feel it in my butt. It happens while I'm accelerating, either straight or turning. It only lasts for a half of a second. Other than that my ride is fine. Any ideas? If I don't give it some umph I don't feel one in that range. |  |  | | 07-18-2008, 09:04 PM | #2 | | NOBODY F's with the Jesus Join Date: Oct 2006 Location: Ventura California Posts: 7,824 |
Check your transmission and motor mounts. __________________ 4 MORE YEARS BABY!!! | | | | | 07-18-2008, 09:35 PM | #3 | | Senior Member Join Date: Aug 2004 Location: state college, pa Posts: 3,431 |
Only at that RPM or starting there? __________________

Okay...for someone who can change his oil, the air filter, and read/reset the computer codes using my code reader, how feasible is it for me to check my transmission and know what I'm looking at?  | | | | | 07-18-2008, 11:04 PM | #5 | | NOBODY F's with the Jesus Join Date: Oct 2006 Location: Ventura California Posts: 7,824 |
Well the easiest thing to do and perhaps you could isolate the problem if you rev the engine with the car in neutral. If it shakes violently, you know it's not a suspension issue. Have someone stand outside and look at the motor and see if it moves significantly when you rev it. You could also go underneath the vehicle and try shaking the transmission from side to side. While you're under there take a look around. The vibration may only occur while the vehicle is under load. This would mean that you'ld have to be rolling. Try getting up to speed and then hold the clutch in or coast in neutral and rev the engine. __________________ 4 MORE YEARS BABY!!! | | | | | 07-31-2008, 08:47 PM | #6 | | Senior Member Join Date: Jul 2006 Location: North Bay, Northern California Posts: 251 |
perhaps you need to rebalance your wheels | | | | | 06-11-2009, 07:51 PM | #7 | | Senior Member Join Date: May 2005 Location: Indianapolis, IN Posts: 228 |
For posterity, I've taken my car to the shop to get the clutch replaced. I drove just over 100,000 miles on it, and I believe having the clutch replaced (along with any other quick fixes they see down there) will resolve this problem. I'll update when it comes back from the shop to let everyone know if this fixed my vibration @ 3,000 rpms (under heavy torque). | | | | | 06-11-2009, 08:25 PM | #8 | | Senior Member Join Date: Aug 2008 Location: Raleigh/Charlotte, NC Posts: 1,233 |
MGBman's had the same problem, it was his u-joint __________________ -Jeff

I was JUST reading that thread! Called my mechanic and told him about the info, hoping he can take a look while they're changing the clutch anyway. That u-joint is just part of the rear drive shaft, isn't it...  That's ****ing expensive on top of the rest of work being done to her. | | | | | 06-11-2009, 09:57 PM | #10 | | Senior Member Join Date: Jul 2006 Location: North Bay, Northern California Posts: 251 |
If the u-joint is the guibo...rubber disk...flex disk? then it only costed me 100 for the part...replacing it your self isn't terribly hard either.. | | | | | 06-11-2009, 10:26 PM | #11 | | Senior Member Join Date: Aug 2008 Location: Raleigh/Charlotte, NC Posts: 1,233 |
no, the guibo is not the u-joint. A u-joint..is a u-joint. If it cost you $100 a guibo...well that sucks, i'm sorry. __________________ -Jeff

Sorry but I'm just now learning what a guibo is (thanks google)...do you mean part #1 in this diagram? http://www.realoem.com/bmw/showparts...05&hg=26&fg=10 I seem to see u-joints near the rear of the driveshaft (near #14 bolts) | | | | | 06-11-2009, 10:28 PM | #13 | | Senior Member Join Date: May 2005 Location: Indianapolis, IN Posts: 228 |

no, the u-joint is one of the metal joints at the ends of the shaft, which are permanently attached to the shaft and can't be replaced individually | | | | | 06-19-2009, 01:07 AM | #15 | | Member Join Date: Dec 2008 Location: NOR CAL Posts: 51 |
so is this a drive shaft replacement? @ 600$ how difficult is this procedure? I got the shakes as well at least its not the wheels | | | | | |
