Should be 85-88.5 (Samurai was first offered to US market in 85)Just wondering why the Lockrite 1510 locker only fits the front of the 86-88.5 model Samurai's? What makes these years different to older or newer?
I want to say yes, basically the same, but with my luck it isn't... I will check the old parts bin when I get home.Thank you.
So the only difference is the amount of pins? The side gears are the same and all? Just weaker because of only having two pin?
The Samurai had two different flange sizes. Unfortunately, that was one of the parts that changed over the 88-88.5-89-90 model years. The lines just used the small flanges until they were used up and then they switched to the large pattern. The thing is, they didn't all change at once. You can find either size of flange on any model from 88 to 90. The good part is that they are all interchangeable. If you get a late model set of flanges (stronger/larger bolts) they will fit an older model Sammy (as long as you also swap to newer shafts). Some aftermarket vendors use newer flanges drilled to except either bolt pattern.The flange size may be different. I had to swap my old Driveshaft flanges on to my new 3rd members. Otherwise it bolted right in.
As written above:What your saying sounds a little wierd. The spider side gears in the diff definitely need three pins, not two, to operate properly. How can you operate them with only two gears?
This is what is known as a 4-pin carrier. (Remember, 4 ends visible outside the carrier)Can anyone please post a picture of what a Sierra/Samurai diff looks like inside the carrier?
Bingo!Ah, I get it. The one with four pins (sticking out of the sides) is with four spider gears, and the one with two pins is with only two spider gears. The more the hears the better, I guess, to give it more strength.
I'm trying to imagine how the locker will fit, because I am planning on getting one, and my Samurai is 91 year model. So according to you, it has only two pins (One actually). Spidertrax lockers have the option of getting 26 spline side gears, or without them, if yours are ok. So how will the locker discs interface with the stock side gears? And is it possible to drill a couple of holes and install the other two pins?Bingo!
But when you install a locker, the locker discs replace the spider gears. The discs sit directly over the pins. Think of the pins as the rebar in a cement pad. The more rebar, the stronger the pad.
