Post 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.

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

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

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.

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).

There was a little slop in the shifting, mainly while moving, but none now. Is the sound coming from the transmission itself, or somewhere along the driveshaft?

Try having someone else shift while you listen under the car to see how far back the noise is coming from. There is a crossmember underneath that you can use as a point of reference. As you can see here and below, the crossmember is roughly where the middle universal joint is (the bolts coming down from the body on the left and right are where the crossmember bolts on). There is also a similar joint at the very rear of the driveshaft.
