Thanks everyone. Roy, thanks for digging up that old thread from MA I read that thoroughly as well as your boler
axle replacement thread. Great information!!! I'll put up a pic of the spindle position unweighted. When fiddling around (2 new Carlisle tires) I noticed one wheel bearing is sloppy so will pull and examine. Process of elimination right
After looking at the threads Roy provided, I will have a close look for camber problems. The old (car) tires that came off are unevenly worn for sure so indicating negative camber problem. The crack I mentioned I think will not lead to the axle falling out as it is held in completely surrounded by steel plate. I'm thinking due to basically no axle travel movement it may may caused these stress cracks? Anyways, one thing for sure new axle due, sooner the better.
I did not have any choice really for new tires using my 13" rims so I went with the 175 80 13 st they had them in stock. They tried to convince me I did not need to have them balanced so I said fine was not up for an argument - so then went to a friends shop and balanced them. Will buy a 3rd for the spare when some extra cash allows. After getting axle upgraded to a #10 then I will start to look for some nice 14" (ranger) rims. If anyone spots a set in a wrecker in bc please let me know.
