OK. Have the bits. The torque spec for the giubo to trans bolts is 150nm or roughly 80% of max for that size/grade bolt. Given they are precoated with thread locking paste, this is unremarkable. The nuts/bolts connecting the giubo to the shaft are dry and the nuts are elliptical locking type. No spec is listed in the manual. Any suggestions on what to torque them to? Max (180nm)? A bit more to account for friction from the locknut? Am I overthinking this?

Had mine replaced today

The Guibo replacement fell into step 3 in my case.

1. Have Ford replace recalled seat belts.
2. Have Ford install water management stuff for air filter problem
3. Have Ford replace cracked guibo

My wagon is at 49,000 miles, so i thought I would take a look a look at that big rubber donut and see how it was doing. Below is a shot of it before the repair

For the record, the service writer said my repair was not finished yesterday because the tech was going to have to pull the driveshaft to complete the replacement. I don't know if that is true or not, but I would make sure I had a clear testimony before I cranked those bolts.

Also, in regards to the bolt torque, would they have the correct torque on them now, before you loosen them? In other words, could you apply tightening force with your wrench to see when the needle moves, thereby determining the correct amount? Considering that they are compressing a giant rubber coupling, maybe not...

They compress steel sleeves molded into the giubo. Said sleeves protrude about 3/16". Three towards the trans, 3 towards the shaft. So with the bolts out and the giubo rotated 30º or so, you get about 3/8" of slack in the interface. There is also a splined junction behind the center support bearing that, should it be needed, might allow further separation. I expect this to be easy for anyone but a dealer mechanic, whose ilk could total a vehicle trying to air up a tire.

Step 4: Order a couple of tools to make it easier.

Crawled under the van to look things over. Tool clearances are tight. Not wanting to wrestle elliptical locknuts with a ratchet and an adjustable wrench, I ordered a U joint for my impact gun and an extra long 21mm combo wrench.

They say new, she gets new.
Where are you getting them for $30 total?
Ford shows the 6 bolts at $12.74 ea
and the 3 nuts at $11.10 ea

Total $109.74

Even with the 25% discount that can usually be had it is still $82.31.

Maybe you are getting non OEM bolts for $30...???

On my invoice they came out to 4.29 for the bolts and 1.35 for the nuts. Too bad it doesn't use deer nuts. Those are under a buck.

Really cheap vendor. 58¢ for the nuts. You have to admit $11 for a nut is clearly some kind of typo.

I don't know- some of the prices I've seen for Ford parts were really outrageous- I looked up some $1 plastic doodad once and they showed $180!


Those Ford Parts Giant guys are pretty good- a few years ago I cleaned them out of every NOS Ford external bypass trans filter they had for something like 10% of their original cost..
Only thing for me is shipping is a killer from the west to east coast.

Figured out the price discrepancy on nuts and bolts for the giubo. Ford packages nuts and bolts in bags of 2, 3, 4 etc. and the price on their website is for the bag. I decided to pick up the 2 bolts for the center bearing in case I need to pull them to make the job easier. Had to buy 4 of them from the dealer I went to. Not a problem as it looks like I'll need a giubo every third oil change.
