LSD rear diff

Can anyone confirm that X-Runners have a Limited Slip Differential? I'm ordering gear oil and need to know if I need the LSD additive. Thanks

 

Go look at the diff housing from the back of the truck. It will have a LSD sticker if it has a limited slip.

 

The small sticker near the top. "LSD oil only"

 

Okay. Now I'm very frustrated!! The owners manual doesn't specify.....

 

Not sure if the 2009 rule applies here or not, call toyota if there is any doubt.

 

My truck is a sport and has the LSD, however I don't have the fancy red sticker for some reason on it.

This is very easy to determine. Jack up your truck so that both rear wheels are off of the ground. Put it in neutral and take off the parking brake.
Rotate one of the wheels going forward and see what the other wheel is doing.
1. If the left wheel is going forward and the right wheel is going backwards, your diff is OPEN.
2. If the left wheel is going forward and the right wheel is also going forward, congrats, you have either an LSD or a locker that's locked. (which you would know about)

I personally like Redline products. They have a great website with an application guide.

I know some prefer to use only dealership products, if so then they can get you what you need.
