I have a feeling the answer is staring me in the face, possibly sniggering at my discomfort, I am stumped and asking for guidance please..
I am rebuilding a Girling front axle. I have stripped, cleaned and readied the axle for new bushes and pins etc. I put the new king pin bushes in and have reamed them with the correct tool. The pins were a nice firm push fit, the axle eyes seemed ok. The o/s stub axle fitted with the 2.5mm thrust washer supplied, once I had thinned it a little on a diamond stone to about 2.3mm. I tightened the cotter pin and all was well. The core plugs went in and I was content.
The n/s similarly went together quite happily but there was a little up and down movement, which I reduced with a shim but there is still a little movement. As I tightened the cotter pin however the stub axle became stiff to move and is obviously not a happy fit.
I understand that the king pin is probably moving in the axle eye as the cotter is tightened but I dont get why it then binds? With the cotter loose and taking a firm grip of the stub axle I cannot feel any movement between the stub axle eyes and axle eye, which suggests to me that the king pin can only be moving to the side rather than tilting?
Any clues or suggestion would be welcome please, thanks in anticipation.
