Help Needed - Shaft & Fans

[Makaveli7]

Hey Guys,

I need your expert help and opinion on my 2005 e46 330ci..

1- I changed my Central Baring and I used a new Original Bmw Baring that looks something like this .. http://thumbs3.ebaystatic.com/m/mVKO...1rUoDQ/140.jpg

The issue now is that the shaft is vibrating a lot now, and the mechanic is saying I need to change the shaft.

Since I didnt have this issue before I was wondering what would be the problem, and from prior experience I know that if you dont put the shaft, the bolts, and everything, in the same position they were before replacing the baring, you would get problems.

If this is correct, can you please advise me if this is reversible and who can help me either balance the shaft again or fix this issue. (Note that Im afraid that if I replace the shaft the issue will still there.)

2- I have a mechanical 11 blades fan clutch, but im getting sick and tired of the OWoooooooooo Noise that is riping away some power of the engine, and making higher noise from the exhaust!!.

I was thinking if its possible to make the swap from the mechanical to the Electrical fan ( I got a quotation from Central in sharjah for 1,005 AED Original Bmw Fan).

Is this advisable considering the weather in dubai and the highways.

If yes can you direct to someone who can help in the installation.

let me take the chance to thank everyone in advance, Im asking this in here because ive seen all the knowledge and talent here and Im sure many of you have either done this or resolved such issue..

Appologies if this is a re-post, but couldnt see it anywhere else in the forum.

How bad was the previous bearing? Was it completely ripped and the shaft was moving around out of place?
In other words, did you have any vobrations prior to replacement?

Did the shop reinstall it properly? Was the shaft dropped? Stepped on? Bent? Stored improperly? Left to hang from one side while still bolted on from the other?
The bolts don't affect vibration, I've tried on my car before, never had effect.

Your driveshaft can't just go bad on its own like that, I suspect the shop danaged it or its been improperly installed.

The fan issue.
Yes. You can delete the mechanical fan and run an electrical unit instead. Its been done before with proven result. You don't need to go with a BMW fan, there's better aftermarket fans available for this specific mod.
Something like PermaCool or Spal electric fans. They're available woth fan controllers as well.

Vibration after a guibo+central bearing job:


a) Torque specs are not followed. Torque specs at differential input is usually neglected. These drive shafts are indestructible, so I'd be very surprised if it turns out to be that.

b) The guibo is fit backward. Common malpractice by many.

c) The shaft was hanging from the transmission side while the job was done.


Electric fans; I'm not a big believer considering our weather. Usually the noise is coming from a leaky fan clutch. You can swap to a six-fin mechanical fan.

If you like and have the time, pass by Das Autoworks for a look-see.

Hi mate,
It sounds like the centre bearing is fitted arss about face or not inline! common fuckup.
A visual check is the only way foward!

My freind drove the car and siad im getting peakyy and its nothing, but I know how she drove and this is not the same...

@SSU thank you m8.. Though I dont know if they bent it, droped it, steped on it, or played cricket with it:P.. The Old central baring was fine, and I still have it with me, the reason I changed it is because it was a tijari, and the one in right now is original :(.

@ Ayham & Shak thank you for the feedback ill try passing by tomorow to das or the X to get this fixed when you guys have the time. Need to finish this for the drive :P

Warm Regards gents

Funniest thing happened on Saturday.. So I googled Das Autworks Dubai.. Got a phone number, droped a call, asked if they open, the lady said yes... Is Ayham in the Garage?? Yes sirr.. can you give me directions... Yes

Got the directions.... Drove and got lost in AL quoz for 30mins.. Got the shop that was called DAS AUTO MAINTAINANCE !!!

But Voilla, the wron DAS Centre that I was trying to locate!!!!!!!!

Not having internet, and having some wisdom tooth problem I went to find the X service centre (Since Ive been there before)..

Got lost for another 30 mins!!!

Went back home and the shaft is still vibrating:(

Sorry guys ill try again during this week (Im an auditor and my clients are taking all my time:( )

The vibrations are only when going from 1st to second gear so hopefully the shaft wont damage??? :S
