when braking x5 jurks forward
 

having a problem.... when braking my x5 lurch forward before stopping, i change the front brakes and rotors but the problem is still there...this action only happen when braking....what could it be?????

maybe ur control arms?

That sounds more like a driveline issue than a braking issue. There have been previous posts on a similar issue before and the majority of opinion was transmission. I remember the fix being fairly easy though. Do a search on it and I'm sure you will run across it. I want to say I saw a post on it between 1-2 weeks ago.

Here's the most recent post I saw:

I am guessing your control arm bushings are shot. I had this issue on my 745 with 80K on it and it did that same thing when braking. It was just the driver side, but I replaced both.

have anyone personally tried these?

OK Know I'm really confuse, which one isn't the control arm, or resting the transmission,

What does it feel like to you? From what you posted, it resembled the lurch issue which is a common problem that has been posted several times on here. I would try the reset of transmission first as it is definitely the cheapest of the two. If that doesn't help you might know to look at something else.

i know now it not the control arm, when coming to a stop i put the truck in N will braking coming to a stop, there was no lurching,i did that a couple of time's no lurching...than i tried stop normal, the x5 lurch each time will braking it lurch but not when braking in N SO it most be a transmission problem... know how in hell do i reset the Tran.....is it key in position 2 for 30 to 45 sec will push down on gas pedal, than start up x5 and run the hell out of it for a few miles...is that it????

???? I did a quick search and didn't find the exact procedure but I didn't search very long. You will find it in here if you do a dedicated search. Sounds like it is the tranny to me too.
