Here's the problem - The pivot shaft on the right side is stripped out. Leaks alot of oil. Can not be tightened, even with an impact wrench. I am contemplating replacing this my self. It appears I would need to pull the ROPS, tire, brake to get to the axle housing. The pull rear axle and unbolt the housing. Need some good advice before I jump into this. Thanks Rick

I'm assuming you mean the lower arm pivot?

If it's like my old Fordson, it's a fairly easy thing--remove one side of the axle "bugle" or "horn"---wheel and all (you can remove the wheel if you like). If I recall correctly, if you remove all the nuts/bolts securing the horn to the axle pig it should slide right out with some coaxing. I'd use a transmission jack on casters or an engine puller on casters to support the axle regardless if the wheel is on or not. You might have to buy a new pivot bolt as it probably beat up, not to mention the hole in the casting being wallowed out. If it's wallowed, don't know what to tell you there. There might be a tapered reapir bushing available---dunno. If there is an oversized hole there a new seal might fill the gap. ....
