I need to replace the 8 spindle bolts on both knuckles. These are the bolts that hold the spindle and gaskets in place on the outside of the knuckle. The dealer can't find the part number. Apparently the diagrams don't show the bolt or it's part number. Anyone what the part number is or a source for either bolts or studs that will fit?

Thanks.
 
Those knuckle studs on Marlin's site are for the bottom of the knuckle to hold the steering arms on (the "check yer nutz" ones). You want the 16 (total) bolts for the spindle? I don't think anyone has any aftermarket studs for those. They don't tend to fail or require replacement (not that I have ever heard anyway). Why do you want to replace them?
 
Why do you need to replace them? They are a very high grade bolt and I don't see how they all could go bad? Edumacate us!
 
One bolt backed out destroyed itself and took out the other bolt heads as it rattled around inside the hub. Which means they can't be removed easily or torqued properly. I'd just like to replace them all for peace of mind. I'd like them by Monday, which is why I'm hoping I can get a part number and just have my local dealer order them from the parts house and have them ready for me on Monday, but if all else fails I'll give C-dan a call and place an order.

When I built my mini-truck and did a solid axle swap, a common thing was replacing the bolts with studs and I got a set when I rebuilt that axle years ago. The purpose of the studs was to make assembly easier. Apparently, they aren't sold anymore. I don't care if I get studs or bolts, but I need something. At least 8 new ones, but thinking I'll probably just do both sides.

Searching around it does seem that nobody does the stud thing anymore on these knuckles, which is weird, because it really did make the assembly a lot easier.
 
I know exactly what you are talking about. Although these spindle bolts are high rated, they certainly can fail. Luckily I only had one fail when I was doing my birf rebuild. It stretched before I had got close to the required torque, but luckily I caught it before it snapped.

I bought a replacement from CDan, but IIRC he doesn't stock them from Toyota, but was able to source an identical bolt from one of his local fastner sources and he shipped it to me with some other misc items I purchased. I will most likely be replacing all 8 of them, the steering studs, and the hub flange studs/nuts when I do my next rebuild.

I'm unsure of the of the thread pitch etc if you need one locally, but Dan should be able to get you a full set.

I didn't think the torqe was that higth for these bolts...

Anyone know the proper torque for these??

It was in my case. I was using a brand new craftsman torque wrench so I know it was in spec. (we can save the torque wrench bashing for the thread that was dedicated to that discussion;)) I wasn't even cranking on it hard, it just felt like I could keep turning and turning the bolt without it getting any tighter.

It actually felt like the knuckle was stripped and I was planning on a long day of drilling and tapping or the increased expense of a new knuckle. I was relieved when I found out it was just stretched and did not snap off inside the knuckle. This surprised me because I thought hardened bolts would shear instead of stretch when they reach their max force rating.

To confirm it was not a problem with the knuckle threads, I put one of the 7 remaining spindle bolts into the same hole and it torqued to spec without issue.

Spindle Stud Kit
When assembling your spindles gaskets does it feel like your all thumbs? This kit contains 16 studs and flanged nuts. With studs installed it's easier to install the spindle gaskets. Gaskets are placed on the studs one at a time, then nuts are install on the assembly.

I like the idea. Real keen.

I just won't buy from the source.
 
He can't find them because they are not in the section of the EPC with the spindle and knuckle. They are in the section with the disc brake backing plate. The part number is 90101-10166.



Now, from some reason these do not show the washer and the bolt doesn't come with one. Go figure.

I'd imagine the washer should be easy to find since it is just a lock washer.


I really like that kit Brett listed, it would make putting the spindle back on a breeze.

I have not heard anything about the source though. Seems like it wouldn't cost that much more than replacing all the bolts like I plan on doing next time I do a rebuild, which may be soon if my buddy buys that 95 we have been looking at.

IIRC trail gear is or once was a mud sponsor.

I had the same thing happen, and CruiserDan said that those bolts were only stocked in a couple Dealerships in North America. It turned out to be faster to order them from Portland OR than to have Dan order them from portland and then ship them to Idaho.

Yep that's pretty much what mine looked like. Now I'm debating going for the studs or trying to order bolts. Is there suppose to be washers? Because I didn't see any washers on any of the bolts.

Washers are not needed in this application and could weaken the connection by providing another surface to move/slip. The stud kit has flange nuts, that setup would be stronger than bolts.
 
I had the stud/flange nuts on my mini-truck and they held up fine. I think I might just order this kit and swap them out. So I assume the studs have to be torqued at the same value as the stock bolts, then install and torque the nuts at the same value?
