    So I've been getting that locker bug again (for my pussy 5 lug yes) and I need your help. I have access to a factory e-locker fully assembled 3rd member from my shop teacher at school. He bought it for his 4 runner and then sold the car before putting it in. We can easily handle the fabrication if it will fit. That's where you come in. I need to know the specs of the TRD rear axle... here's a table to help

    THIS CHART IS FOR '95.5-04 MODELS ONLY!

    The axle code for your rig can be found on the manufacture's sticker located on the driver's side door jamb as follows:
    First digit:
    A = 7.5" ring gear
    B = 8" ring gear
    Next two digits:
    01 = 3:42
    02 = 3:58
    03 = 4:10
    04 = 4:56
    05 = 3:15
    06 = 3:91
    07 = 4.30
    Last digit:
    A = 2 Pinion, Open
    B = 4 Pinion, Open
    C = 2 Pinion OEM Limited Slip
    some '98-00 models have shown a BO code of "???" on the door plate; so far this turns out to be a 3.91 gear ratio, at least for the 5sp. RZN171L-CRPDKAB with factory 31s/265s should be 4.56 with the AT.
    Edit by Ed Quinones on 10-7-05: I used to own a 99 Prerunner ext cab 2.7L with auto tranny and gear code of B07A. It came from the factory with a 4.56 gear ratio.

    Mine is A02A, which is a 7.5" ring gear. I believe the TRD have the 8" ring gear so I may be SOL. Would the 8" ring gear fit in my 7.5" housing? I really hope so because I think I'll get a pretty good deal on it and I'd get 4.10 gears out of the deal too. Thanks in advance for anyone who can help!

    I think that the only way to get the 3rd member under your truck is to have the whole rear differential and housing from a trd truck. . . then you're stuck with 6 lug in the back and 5 lug in the front . . My advice is get a mechanical locker, that's what i plan on doing. Probably a powertrax or something like that.

    None of your options are cheap.

    You can get an Limited Slip, I pretty sure you can look at 7.5" LSD's for Supra's etc.

    or

    You can get an ARB. The same part number that fits the front IFS will work for the rear 7.5

    Another possibility. Run a TRD rear with either 1) custom 5 lug axles, or 2) Re-drill the 6 lug axles for 5 lugs. I once got a set of axles redrilled for a hot rod to change bolt patterns.

    Richmond Gears makes a couple nice options. Lockright or a no-slip. I have a No-slip in mine and i dont have any complaints so far.

    I wouldnt recommend Lockright for a daily driver either, but the road manners of the No-slip are alot better.

    I dont necessarily think it would cause any problems for a daily driver, i just think for IIRC $100 more you can get the no-slip. From what i have heard (ive never ran a lockright) it has better street manners. Does your lockright chirp the back tires when you make a tight turn?

    No chirping at all. It engages when one wheel spins and traction is lost. It's brilliant really. Sometimes on ice I have to let off and get back on the gas but it keeps me movin forward.

    Hmm they sounds pretty similar then if you ask me. This is what i found that differs between the two.
    Edit: I didnt truly know the difference sorry.

    No-slip

    These Powertrax no-slip traction systems are the latest design in traction-adding differential technology. They combine the smooth operation of a limited-slip differential with the traction performance of a locking differential. A precise synchronization mechanism eliminates the ratcheting sounds typical of other locking differentials. Special gear and spring designs reduce the backlash and, therefore, the driveline windup. Only ultra-strength material that is 67 percent stronger than titanium is used. Installation is simple because no ring and pinion setup is required. In addition, no special tools or oils are needed. Step-by-step, model-specific instructions are provided with every kit.

    Lock-right

    The Powertrax Lock-Right and Performance Lockers' straight-line performance is equal to a solid spool axle, yet automatically unlocks to allow full differentiation in turns. The lockers also reduce the excessive noise, tire wear, and drivetrain damage associated with other lockers. Made in the U.S.A., Powertrax lockers replace the spider gears in your differential carrier without affecting your ring and pinion settings. The whole job can be done in your driveway with common hand tools in a couple of hours. A carrier is not included.

    Looks about right except the easy install part on LSD. I did the powertrax on my jeep myself easy no problem. I let a professional do the LSD, waay to much involved for the average joe.

    Did any other vehicle come with an E-locker on a 7.5" ring gear? Like maybe a 4 runner? I don't know what it came out of for sure.

    What about directly swapping the rear axle from a Ranger? (it would be treason, i know.) I'm not sure about how well it would fit etc etc but at least you could use the wheels you already have?

    The Ranger GTs that were made around 1986 had a "Traction-Lok" limited-slip differential with 3.73 gears.

    And the newer FX4 level II has a 31-spline 8.8-inch rear axle with a Zexel-Torsen limited-slip differential. They started that package around 2009.

    Well I guess I'll stick with the lunchbox locker then if I want to lock it up. The 3rd is for sale now... if anyone's interested I can ask the owner for you.
