I'm trying to replace swing arm bushings on this machine, I got the clutch and all off, removed the brakes. But when I go to turn the swingarm bolts, they just spin. Either way, tightening or loosening. Any suggestions?

 

Look at the parts break down. There's a large nut on either side(item#12) 1996 Polaris XPLORER 400L (W969140) Swing Arm/Shock Mounting Xplorer 400L | Cycle Parts Warehouse

 

I see the one on the clutch side but not the brake. Is it under the chain slide?

 

Yes it's in the yoke of the chain slide,kinda hard to get a wrench on. Can't remember off hand but think it's either 3/4" or 15/16" on the nut.
