Review: Kind of a pain but worth it - I installed this locker with yukon 5.29 gears on my 2018 toyota tacoma trd sport 4x4. You need to call yukon and ask for the part # for the bearings that go on the locker. You can also get them from toyota I'll put a picture of that part number for toyota. Love the setup though
Review: it’s not too bad. Best auto locker out there imo - I put this in a full time all wheel drive land cruiser FZJ80 front diff. I don’t daily drive it, but it is really smooth. The only time I get some steering input is when abrubtly letting off the gas in a turn. Even then, it’s not too bad. Best auto locker out there imo. I would not hesitate to put this in the rear diff on a daily driver. I have one in the rear too, and that one is completely unnoticeable.
