setup of lockright is FRICKIN SIMPLE!!! I have never installed something as easy as a lockright. you don't have to reset the gears or anything, just mark everything so you put it back exactly how you took it apart.
I have both mini-spool and lockright. I ran my lockright for a long time in the rear end and it was OK. I hated the ratcheting and banging and all the loud knocks that are inherent with a ratchet style locker so I tossed it up front and put the mini spool in the rear. If you run around town, get the lockright. If you are dedicated trail rig, there is nothing nicer than a SPOOL...if someone around here has never ran a spool or welded, don't listen to their advice about it on the trail...the spool is far superior in reliability and simplicity in the rear end of your vehicle. I will never run an ARB or anything like that out back because of the reliability issues...you can't go wrong with a spool.
Again spool it if it is a dedicated trail rig.
turning on slick rock...Schmoe...give me a break....
If you need help installing something in a zuk, talk to me, I have done it all a half dozen times...I have done t-case gears, lockers, axle bearings, transmissions, motors...the works...but if you are changing gear ratios in your diffs...take it to a pro like rocklogic, or Andy at 6-states....andy has been doing diffs EVERY day for years...he knows his stuff. Rocklogic specializes in jap parts so they know their stuff too.
other than that....a samurai is the ultimate DIY vehicle. Cheap and easy to work on...if you need lockers installed, bring me the diff and save yourself the shipping to oregon...usually about 30$ for a diff. If you buy zuk parts, get them from trailtough, they are the best guys in the business...dont even say the RRO word around me...I get irate.
Buy me a pizza and I will teach you how to do it in less than an hour....I like helping out my zuki brethren.
I am trying to sell my parts in my axles so I can go d-44s so let me know 791-0377
