Driveshaft bolts

[calmac06]

Anyone know the thread/bolt size of the bolts for the front d-shaft?

 

[calmac06]

No takers?

Come on, someone has to know

Sorry I dunno exactly, but the back ones are a little specialized cauz its so long but the front one is pretty generic and you can probably even get them from the Jeep dealership cauz the front axle is a *******ized Dana 35.

Are you in need of bolts for it?

 

[calmac06]

Yes...

Yeah, I need the 6 bolts around the cv-joint/transfer case side... I guess I'll just go to the hardware store and hunt and search for some, or go to the Ford place if I have to...

While I'm at it... I guess I'll go ahead and say that I also need a black front right fender for my '97 Sport. Anyone have one?

You need all six? I think I have six. You're welcome to em if you pay shipping. They came off of my 97 Mounty but I think they should be the same bolts.

I'm going to try and find some today, I'm anxious to try out my 4wd... it's been disconnected since I bought it! Thanks, and if I don't I'll send you some money for yours!

PM me if you need em and give me your address. I'll see if I can dig em up and ship em to ya and you can just send me the cost of shipping back when you get it.

Jamie, I really appreciate your help but my impatience lead me to the local Napa, Ford, Advance, Autozone and then to the Fastenal. I had to buy a whole sack of bolts, 50 to be exact, but they were only $20, Ford wanted $34 + tax, and they were the only place that had them, or anything close, so I bought the 50. I guess it costs to be impatient sometimes. On the plus side, I did the Brown Wire Mod today, and am very pleased with the result! Thanks a lot though!

Just in case anyone comes across this and needs to know the bolt size/thread for the 6 transfer case side bolts they are: Metric M8-1.25x55 rated 12.9

It's not a standard head bolt, or hex head... it's like this

I just did a transfer case replacement, and put the original bolts back in until I can replace them. That leads to questions:
1. Are they "stretch" bolts like the head bolts?
2. Can they be re-used?
3. Is there anything really special about them that they need a special bolt, or can the high strength 12.9 socket head cap screw like the one in the previous post be used in place of the "factory" bolt?

They are not torque-to-yield bolts. They can be reused. I'd put some Loctite on the threads. I don't know what the torque spec is, but I believe they don't have to be super tight. I guess maybe 30-35 foot pounds max. They're pretty small.

Update: Apparently torque spec is just 22 foot pounds. Like I said, not super tight.

As a matter of fact I did need to know that.
I have to take the output flange off this spare transfer case and I need to bolt something to it to keep it still while I swing off a 5 foot breaker bar on the centre nut.

Mine appear original and have regular 8mm hex heads, with the usual 'automotive' flange underneath (replacing a washer). They are also full thread (which shouldn't matter, because only the last 10mm or so engage the transfer case flange). The stamped grade is 10.8, which seems to be sufficient for the application. Each two are inserted through a short 'yoke', instead of directly contacting the CV case. This probably because the CV case is too thin or too soft to take the pressure directly. The Ford manual says not to reuse these bolts, perhaps because their new ones come with some sort of adhesive pre-applied, and that stuff is a mess to remove. I see no reason against reusing them if they are cleaned and medium-grade Locktite applied prior to assembly. Torque spec is 22 ft-lb.

why would you use RTV instead of a thread locker?

 

[1998Exp]

Oops, a slip of the tongue. Meant to write Locktite, of course. For the benefit of whoever finds my 2 cents' worth comment and decides to use it, I corrected the original posting.
