Guibo bolts

Post by T.Hanson »

I put the guibo bolts in bolt heads in the back. Then I see the book has them alternate. One of my cars has had them all bolt heads rear for eight years, no problem.

Tell me it doesn't matter, because putting bolts in a guibo without the clamp tool is right up there for stupid, angry, frustrating.

You have them in the way the Haynes text indicates. Pictures show other way.
I just pulled mine and the nuts were forward......but someone had replaced the guibo...it looks new.

The Haynes I have has three forward, three back. I.e., bolt the guibo to the driveshaft flange with the heads against the guibo, nuts against the flange. That way the shoulder (non-threaded) part of the bolt is inside the guibo sleeves.

Like Hanson said. three inward and three outward. With some gear boxes it's possible to hit the case if you put them differently. Just turn the shaft and if you don't hit anything it's all good.

I'd tend to agree, from the aggravation necessary to turn any around. Especially without the guibo squeezer tool. Dropping the exhaust and drive shaft is heavy business.

Still, the reason they are three and three is the little deal about the bolt shoulders, no threads, going through the guibo and flange.

Maybe I'm missing something...the bolts are only threaded on the ends just enough for the locknuts so if there is no interference with anything why would the direction matter ?

You are absolutely right. Given the transmission flange and drive shaft flange are the same thickness, guibo fits between and the bolt shoulder is long enough to cover the distance either way, who cares which way they fit ?

Why I entertained another opinion without doing your visual, I don't know. I guess the engineers liked the idea of mounting the guibo to the drive shaft flange first, bolt heads on the guibo side, who knows. The odd part is, looking at the assembly from the side, the nuts on the transmission flange get close to the trans case. Good place for the thinner bolt heads, save they can't be inserted from the trans side.
