Help Finding Driveshaft Bolt ID

Trying to find the proper bolt that fits from the transmission through the flange and into the propeller shaft yoke. It has the splines which step down to the threads.

17mm head of bold, 11mm threads, 14mm nut. I'm trying to explain it to the Toyota parts department and not finding anything. Anyone know the part #?

Thanks.

 

Year? Engine? Transmission? Sub model?

 

2006 Double Cab SR5 4.0

 

2wd? 4wd? short bed? long bed?

 

4wd short bed

 

It's looking like a wrong!

37140A in the diagram.

Correction 90105A0075

 

Or here a 37100A

 

OP said he had 4WD and this is for a pre-runner.

 

The dealer just called and said they only sell the whole flange and not the bolts. $180 seems absurd for only needing one bolt.

 

Good catch, Thank You.

Same diagram, same parts.

 

MSRP is $1.90.

Part Number: 90105A0075

If you can get that entire flange off you might be able to get a local shop to press a new stud into it for you. Its just like a wheel stud.

If you look at the lower right corner of that last diagram posted you can see the "nut type" they are referring to. This version has the studs pressed into the flange from the transmission side and the shaft is held on by the nuts. This is what the OP has.

 

Just throw a grade 8 bolt and nutt in there for the time being . A little lock tite and you are good to go . I believe it will fit just fine

 

The splined section is just there so you only need to tighten the nut, on the differential end it is a nut/bolt setup. You'll just need a box wrench to hold the bolt from spinning during assembly. Nothing wrong with putting a nut/bolt on the t-case end, I've had bolts/nuts instead of the serrated bolt in there for about 10 years and haven't had any issues, blue loctite on assembly:

90105A0075 – Driveshaft Bolt
90178A0045 – Driveshaft Nut
9020111013 – Driveshaft washer

 

Even though the splined bolt I have takes a fairly big step down from the spline section to the smooth/threads section? Won't there be some play in there?

 

none I have noticed.
