Front drive shaft flex disc (guibo)
 

Hi all,

Has anyone ever replaced the FRONT drive shaft flex disc? Watched few videos and read a bit about it and it seems that without removing diff or trans case or cutting it in half it is not possible...

Any advice/ideas appreciated!

What model are we talking about? Usually on these the front propeller slides a bit in the transfer case and flex disc can be easily changed.

I’ve got 3.0l diesel e53

So you are saying I should be able to slide it into trans case enough to take the flex disc out?

I don't think you can push the front prop into the TC due to the way the dust cap loads axially.

I've heard of people not using the centering pin on some variation putting in but does that mean you have to sawzall to remove?

I would not have an issue with destructive removal of I could find a YouTube video to change It showing that method.

Destructive guibo not prop

I recently installed front prop on e90 and that allowed overshot into the TC to make it easy and I think the same to the rear, or just dropping the CSB gave me plenty of room.

Back to e53 front prop. I also would not be against possibly deforming the dust cap to gain 1/4-1/3" to release the guibo.

IIRC it was just this easy.

I was going to say. Front driveshaft service is cake. Rear is the difficult one. When I did my driveline service it took a couple hours for the front. Took a couple weeks for the rear. Ugh, there's a thread as to why. :rolleyes: A seized centering sleeve was involved.

Seized and anything no fun when fixing a car.

Just changed out my front driveshaft. I was thinking about posting something. But literally is this easy!

Have you had any problems and had to replace any of the parts listed in this instruction?

Yeah...I replaced the whole assembly including a new guibo.

The OE guibo rubber was all micro-cracked. But my main concern were the splines on the driveshaft as they were wearing out.

I'm going to post a new thread with pics...

Are the front wheels supposed to spin freely with vehicle on lift and transmission in neutral?

I’m working on a 2000 X5. Replaced the front suspension and axles. Looking to replace the front guibo as well. I have the vehicle on the lift, transmission in neutral. Front wheels are locked up. Rear wheels spin freely. Start the vehicle and put it in gear, rear wheels spin, front wheels don’t.

No known issues with transfer case.

Any help would be appreciated.

On pre x-drive when all wheels in the air you should be able to turn one front wheel by hand the opposite should turn the opposite way.

If driven by the engine the rears should turn but not the front. The TC has an "open differential" that sends ²/₃ the torque to the rear wheels so when no load just the rear will spin. DSC should hit the brakes in the rear and cause the fronts to turn if you apply power but I think at idle it might not.

Thank you for the info.

I figured out my issue; the axles I installed do not fit my vehicle.

Before 04/2000, axle hubs are 2mm smaller. I have axles built for vehicles after 04/2000. The ones I have are bumping up against hubs, instead of seating fully into the wheel bearings.

Ouch I have seen that issue in reverse (finding the matching hub for existing CV)
