I’ve done my research and spoken to some of the older guys in my astro-club and have had a couple of suggestions given to me.
I’ve decided to fix the ALT by replacing the nylon stubs with shielded bearings of the same diameter.
As per this post below:

However I would love some suggestions on fixing the AZ motion.
I have read that "Felt Pads" are good?
Has anyone had any experience with these? I would love to hear your thoughts on this..
Someone also suggested a Lazy Susan to be installed, but I don’t know where to start with installing or even getting the parts for it.
Any other ideas guys?
Really appreciate your advice..
Cheers,
Ash

hi ash i had the same prob with my 8" dob the teflon pads are stappled there and are cheap.
i went to my local plastics factory,they sell teflon,they cut me 3 pieces 25x50x5mm and 1 50x50x5mm.counter sunk the 3 smaller pieces so the stainless steel screws didnt pretude screwed them to the outside edge of the base and the 50x50 drilled the centre to allow base bolt to go through,this takes most of the weight of the scope.bolted base back together and the az movement is smooth and a pleasure to use without any sticking.
when buying the teflon its bloody expensive and they had a couple of different thicknesses,i choose the 5mm one to work with and was able to counter sink screw heads,also bevelled all the edges about 1.5mm to have nothing catch on the base
hope this helps you or other iis members
