Is the level 10 transmission enough or would something even better be needed?

How much would it cost to develop a better transfer case.

I feel like the xi has huge potential but I want to look at total cost or if it would even be possible.

20k USD or higher?


Thanks

will probably have to wait till shivs XI customers are over 600-650 AWHP to see what starts breaking. their is a few at 500-550 with ST that are going strong
there just is not enough people with deep pockets to test it out....Yet

does anyone have one of this motors broken?
If you could send it to me in Croatia I found one company which told me they can produce this worm gear and they told they usally make also the other part to which this worm is leaning on....Anyone interested?
Also an old part would be great if you have

I have had my 335 for less than a year and have had this noise the entire time (You can hear it: http://www.e90post.com/forums/showpo...36&postcount=1 ). I didn't think much of it until I had the car checked by my mechanic yesterday and he said it is the actuator motor going bad. The light isn't on yet and the system works properly but it sounds like it will eventually fail and the mottor will have to be replaced. I am running almost stock, only DCI and Alpina B3 TCU flash.

I see there are few of you guys who had that problem and had to replace the motor. Is there an after market re-inforced version of it or I will have to just replace it with the stock unit when it goes bad?

I have contacted company who can make reinforced one.But it seems that no one have any old motor to send it to me.

I'm sure it's a bit late but I'm in for this...with the torque I'm making its really just a matter of time...

Any updates on this thread? It's over a year old...

[Carl Morris]

No updates. As soon as someone breaks one and then sends it to Jack, progress can start on his end. He doesn't see any point in messing with them until people are actually breaking them. He's got a line of GTRs out the door that he's busy with until then.

[knissel]

What about the x6m xfer case?

[Carl Morris]

Nobody has looked at one yet AFAIK. Same thing, though...break it and I'm sure somebody will be willing to take a look at it.

My 320d xdrive is 177hp and 71000 Kms.. ONLY

I was used to hearing that "clack" noise under the car as it gradually appeared until I saw 4x4! and ABS defaults displayed

So I took the car today to my local garage who quickly found out my actuator had been worn out just the way you show on page 8
The actuator is BMW part 27107546671 and I beleive E9X have the same as mine.
Just like some of you, I will have to pay a 800$ bill to get the part replaced by the same S***ty one.

I just can't find out what I have done wrong to make this part last so short...
No crazy start, no ice racing, just me driving my touring daily as any family man does.

[Turbo TA]

So anyone have an upgrade for this worm gear drive? Keeping this thread alive for the AWD crowd.

[Pascal]

Got my car back today from the garage, this hidden defect has cost me 885$
For that price, I've asked to keep the actuator in order to show you and the people who promote the Xdrive at the skiing resorts in France

[Ilyas]

Dumb question, but what's wrong with it? Unevenly eaten horizontal worm gear?

[Pascal]

The problem is that this worm gear screw is knackered.
This may come from a TOO frequent actuation of the Xdrive.

I have just been told that a BMW PuMA case would blame the asymmetrical wheel mount..
Wider rear tyres give a bigger rolling resistance and would make the transfer box work more often.

Can the people in this thread who once had the problem confirm wether they have asymmetrical tyres? (or not)

[gray boy]

what is there in the Transfer case that would yield brass looking material in the oil i drained? is there a clutch ?

[gray boy]

has everybody on this thread gone silent or died?
looking for info on brass materiel in my TC oil,, anyone seen this?

I guess no one cares anymore. It is easier to buy new than repair obviously :/

[skier_du]

Just a quick update, someone has finally made a replacement worm gear.
