DIY - guibo joint / flex disc / universal joint replacement procedure thread

Feeling some drivetrain/shifting slack - and my car being at 138K miles and 8-ish years old - I figured I'd go ahead and replace my guibo joint / flex disc / universal joint. I haven't yet seen any pictures on doing this yet, so I figured I'd go ahead and do it / post pictures.

The basic procedure is:

1. Drop exhaust system
2. Drop heat shields
3. Drop transmission mount
4. Drop driveshaft (CV joint at rear, center mount, then guibo joint)

So far I have the exhaust system down and the heat shields off. Had to take the car down to shut the garage door, but will hopefully have it in the air again and finish in the next few days.

Because the space in which I chose to do this is limited, I'm going to make an attempt to skip #3 and replace the guibo joint without dropping the transmission mount. Stay tuned for updates.

See pictures / procedure --> here.
 

Let us know if you feel a difference... Great thread BTW, I'm not a DIYer but I'm sure this will be useful to many members.

I really really really appreciate this Keif!

wow what a rip

it's really like $150 for the guibo. How can they justify $850 in labor? that's like 10 hours worth of labor at most shops

Hi There

Who do you have warranty through and what does it cost. I have an 05 745i with 68K. Wondering about a warranty for it

+1. If I had a lift, this would almost be a trivial task.

Still all kinds of jealous of your pit!

Could you please list all the parts needed to do this job? I am going to get all the parts together and have my mechanic do it.

Thanks!

The guibo joint / flex disc / universal joint, part #2 here was the only part I bought.

Tonight I took the driveshaft down, put the new guibo joint on, and bolted the driveshaft back up. Tomorrow I should be hanging the exhaust and bolting everything back up. Also, you do NOT have to drop the transmission mount -- there is a gap where you can hold the necessary bolts at the guibo joint with a 16mm crescent wrench with the transmission mount in place.

Looking for a fire extinguisher, then I plan on it. =]

Very cool. Been thinking of tackling this one myself - you beat me to it!

I just got mine replaced yesterday under the SIB that covers the E65, otherwise it would have been about $800!

How did you go about doing this and did you have to pay anything out of pocket?

EXCELLENT write with pics & all! Finished up yesterday & gotta say the most PIA part was my exhaust bolt rusty as hell had to cut the off! I also have mention I removed the transmission mount it makes it 100 times easier to take off guibo as long as you use a ck to support the tranny to lower & raise back up much easier this way! I unfortunately was unable to unbolt rear drive shaft that top not was unreachableto get a good torque on it but no biggie I just attached new guibo to the tranny then attached drive shaft to new guibo with out taking it down!!! & honestly my old guibo didn't look that bad!!!

No go on the video without exhaust -- I couldn't find a fire extinguisher that wasn't behind glass. =( Next time I'll come prepared.

Finished everything up last night. It helps to have a second person when hanging the exhaust, so my dad came over to help. After hanging the exhaust in its rubber mounts, bolting everything back up was very easy. The exhaust system is sealing well and I have no parts left over.

While the old guibo joint didn't appear to have anything but hairline surface cracks in small places, replacing it definitely tightened up the little bit of slack in the drivetrain I felt when shifting and stopping/starting. Very happy with the results.

I will post up a few more pictures later today or this evening in case anyone is interested (mainly of the driveshaft and its various joints).

Final pictures posted. Will label and add descriptions and stuff later tonight.
