Remove a seal and you will know for sure.
I’ll try the bearing seal. The new bearing dimensions are the same as far as thickness. Old bearing has a step new one has snap ring only difference.Either the bearing is to thick for the Axle housing end , or the lock collar is hitting the seal.
What’s the reason they won’t seat just curious ? Imprint test I did said there’s clearance in the middle, axle seal has room.You must insert BOTH axles to test the clearance between the housing end and snap ring. If the axles are made to the stock length, they will not seat unless an 1/8" shim is installed.
He said there is no thrust block.The center thrust block slides side to side. If you install both axles, the problem will become obvious.
Trust me, those spline DO NOT taper down.So I took the third member out. The actual splines inside tapper down at the end preventing the axles from seating. Hard to tell in there but that’s the issue have to shave them downView attachment 1715817374
There’s a solid ridge on the splines (neck down tapper/ beveled )inside the third member that won’t let the axle through to the center pin. I always see threads that don’t follow through with issues that the person is having. Well this is the issueTrust me, those spline DO NOT taper down.
I believe your expertise but whatever it is it’s not letting it through . May be hard to see in pictures. It will be coming apart for a 3.91 gear and I’ll have the ring and pinion show inspect it. Thanks for your helpWell you can say what you want. I’ve refurbished more cone Sure Grips than there is days in a year. I bebeive believe what your pointing at is one of two metal plates that the springs set on. Not sure by the picture. The axle slides thru the side axle gear then thru the cone that does the locking in the rear. Unless your SG is damaged.
