Hello, if anyone can help I need some information on how to replace a front wheel lug stud on a 1997 T100. I have looked at videos online and they all have you take off the rotor or drum brake cover in order to access the lug studs. In this particular case it is not the same. In the videos I have seen the rotor or drum brake cover over the lug studs where as in my situation they are open from the front but there is no clearance to pop them out in the back. I am hoping that somebody on this forum has a suggestion that I can use. Any information would be greatly appreciated. Thank you in advance!

You have to remove the hub assembly from the spindle and the hub from the rotor as the retaining bolts are on the back. You might as well inspect/clean/repack the bearings while yer in there. You will need the rear seal, part number 90311-50005. ;)

This is the response I was expecting but hoping there was an easier way haha. Thank you for your input, if you happen to have any links that show how its done that would be extremely helpful. I looked all over but couldn’t find one for this specific case. That part number will definitely come in hand.

See post #3. 👆
Yup I was responding right when you sent this message. Very helpful post.

  • Jack up the truck and remove front wheel.
  • Unbolt the brake caliper bracket (2 bolts) and remove it with the caliper from the rotor.
  • Hang the brake caliper with wire or string so there is no stress on the brake line.
  • Remove the center cap, cotter pin, and lock cap.
  • Remove the 30mm nut.
  • Pull the hub and brake disc off the knuckle. The hub is bolted to the brake disc.
  • Unbolt the brake disc from the hub.
  • Drive out the broken stud and press in the new one!

That 30mm nut controls the preload on the wheel bearings. So you'll need to look up how to do that when you reinstall. Toyota Pickups have a very similar chassis, so use that info if you can't find stuff for a T100. Or you could DM me.

Cheers!

Hello again! Today is the day that I plan on taking on this project. As I am gathering supplies my biggest question is with this 30mm nut that CaptainNonsense was referring to. Is this best to be taken off and reinstalled with pliers or a socket? I've seen a video where they took it off with big pliers but for the reinstall I want to make sure that it will be on tight. In this same video they held the nut with the pliers and then spun the rotor counterclockwise until it would no longer spin. Thank you everybody in advance!

Also if you would happen to know the name of the seal that I should replace? I'm on my way to the auto parts store now and am going to buy it.

Inner Hub Seal, maybe? Guessing that would get you close anyway. Probably already figured that out though based on the age of this post!
I believe it was something along those lines. The guy at the auto parts store helped me out. Appreciate everyone’s help I’m finishing up the job today! Lugs studs are completely in and just need to put everything back on!
