I have on 02 Tundra and I want to put a limited slip differential, is it the TRD Edition that has one? And it it a straight bolt on, or any mods? Also, is it normal for the oil gauge to increase and decrease depending on the rpms or is it suppose to be stable when its on? Thanks guys

Thanks man, I remember I had the same situation in my old mustang, but for some reason in the back of my head I thought that it stayed stables at all levels of RPM.

My 2004 is not a trd, but is a 4x4 and came with the factory LSD that was quickly removed and replaced with a power trax locker which was removed for an ARB air locker..

As for a a straight bolt on...that depends on!! is it a 4x4,

are you replacing the entire 3rd member or just the diff? and are the gear ratios the same?

The factory LSD is ok on the road and so so in mud or sand, and sucks for any rock crawling...JMO

I want to replace just the rear diff. It's 4x2 and I just want to use it for street use. And skid once I get off work if nobody has answered, I'll try to find that out for you.

thanx bro,as far as my oil guage goes,it stays steady and true,even at 100mph loaded with bikes on our way to the dez,but then again i only have the 4.0 6 so it may be different for the v8.

If your replacing the diff then it's going to be a pita...and you will need to remove the gears to swap the LSD and reset the back lash....

If you swap the entire 3rd member all you need to do is remove the axles, the driveshaft, 12 nuts that hold the 3rd member in, clean the rtv off swap the new or used 3rd member reinstall the above, bleed the brakes and your done, it's about 1 1/2 hours at home...

All 2wd and 4wd T100's, '00-06 Tundra's, and Sequoia's use a newer/stronger 8" 2-pinion diff.
Tacoma 4x4's and Tacoma PreRunner's that don't come with the electric locker (aka "non-TRD), as well as V6 Tacoma 4x2's also came with this diff.
This diff commonly and mistakenly called an 8.4" or 8.25" diff, possibly to imply its extra strength.
The ring gear actually measures 8". The extra strength of this diff comes from the bearing cap/truss and large diameter pinion gear shaft.
LSD's available is the TRD/Kazuma clutch-type 3-pinion LSD, the
OEM 4-pinion Tundra TRD LSD, and the Detroit Trutrac.
Lockers available are the Powertrax "Lock-right," "No-Slip,"
ARB Air Locker, Detroit Softlocker.
This diff cannot be fitted to an older style 8" axle because it uses a larger diameter mounting bolt pattern and because more space inside the housing necessary to accommodate the large bearing cap. The different bolt pattern also makes it very impractical to swap in an electric locking Toyota diff (the whole mounting flange would have to be re-done using a special jig).
- Carrier bearing truss and newer housing adds significant strength over V6 and 4cyl diffs
- Uses V6 carrier bearings, larger pinion bearings
- Uses shims for backlash adjustment instead of threaded adjusters
- Twelve 12mm Ring gear bolts
- 10mm axle housing studs with 14mm nuts
- 30 splilne axles
- 30 spline pinion


the above and more can be found here.......

Thanks Nytrous, I'll do that then, that is once I find one. Tampa Bay doesn't have many junk yards that carry Tundra's. Don't know if it's because they are such good trucks that they don't break or what.
