I'm doing a rotor install for a Toyota 4Runner (1996) and need to know the size of the hub nut right below the dust cover. Anyone, please let me know asap!

This is for someone on another board so TIA

 

Toyota's have two sizes, a 36mm or a 54mm.

 

How do you know which size you have or it is either or, thanks for the fast responce

 

Pull off the dust cover and measure it. If it's close to one or the other, it's that one. The 36mm one is about the size of a half dollar coin, the other one is considerably larger.

Were it a Tacoma of that year, it would be a 36mm, but since it's a 4Runner, while I suspect it's still a 36mm, I can't say for certain. The differences between 4Runner's and Tacoma's catch me off balance from time to time.

 

Thanks man, your truck looks bitchin in the avatar

 

Thanks! I use a few photos from that series as the main images on my web site. I was fortunate to have several photographers in good positions when I went through that stretch

 

I know the hub nut is 54MM for 2nd Gen's, but that may not really help you. Are you doing this on a 2WD 4Runner? On a 3rd Gen 4WD, I don't think you should have to remove a hub nut to remove the rotor.

 

Sorry its still early in the morning. But if you are trying to take the rotor off, you don't need to remove the hub nut.

 

Yep, you only need to remove the brake caliper to remove the rotor. Very easy.

 

Thanks guys, was asking this for a member on another board 4x4parts.com

 

Actually on the newer 3rd generation and a 2000 Tundra that I've worked on all have 35mm nut...

 

There's been some extensive argumentation about that on several boards I frequent, including this one. I have always used a 36mm socket on the rigs I have had to pull shafts from and it has worked fine, but some have bought a 35mm and found that it wouldn't fit without grinding. Others have purchased a 35mm and found it fit perfectly.

A year or so ago there was a thread on the TTORA board where 100 or so members chimed in with their findings and the consensus seemed to be that the nut was really something like a 35.5mm. A 36mm works as will a sloppy 35mm socket in some cases.

In looking in the shop manual, Toyota refers to the nut at the "axle lock nut" and lists the torque setting at 174 ft/lbs for it, but of course, they do not specify it's size

Yet another of those Toyota quirks we know and love

 

I use a 36mm. It is slightly loose, but in that size it works fine.

no wonder the damn thing is so hard to get off.

 

My 36 mm socket was too sloppy and a 34 mm would just barely fit the end of the nut, I finally had to go out and purchase a 35 mm socket and it fit perfectly. Ironically the nut is kinda of tapered, but I didn't like the sloppiness of the 36 mm, considering the torque requirements.
