Yeah, it needs to be as square as you can possible get it and centered on the axle. I remember on the 300, I had to be careful where I welded because of the seals. I had to grind the welds down smooth because the ring gear had a hub on it that slides over the axle and that's where I had to weld and that's also where the diff seals, sealed at. It's been a long time, but I believe I unbolted the diff case and separated it and put the back side of the case on the axle and then slid the ring gear over the axle and positioned it where it goes and welded it. I then ground the welds smooth and made sure there was no weld where the seals would be. I then slid the other half of the diff case on and bolted it back together. I had to take it apart like that, so I wouldn't melt the seals in the diff when welding. Since the 450 has the axle tube that runs the full length of the axle, it may have to be done a little different, I'm not sure.how did it work out? of course i'm sure it'll have to be as square as possible, anything else to look out for?
the spline on the rear axle is worn in the middle causing the slipping. is it possible for the spline in the pinion gear to still be good? if so could i install a new axle and be back in bussiness?thanks
It held, it was on a Fourtrax 300 4X4.how did it work out?
