Thanks Bob. I had another look at it with my friend. I have up + down play on the inner CV joint as well as the in/out play that we're saying is normal. When I grab the inner cv tripod housing and move it up / down it makes a noise, little clunking, like the same noise with the in/out play. My friend reckons there should be no up/down play and so i went ahead and removed the driveshaft to investigate further. I have up/down play on both but I removed the passenger side as it is the worst.
I'd appreciate your thoughts on the below pics below and my questions on them.
Should I have up / down play on the tripod casing?
Is that bearing rub mark highlighted in pic just normal mark or is it a sign of something not running straight?
It's not very obvious in the pic either, but there a little blue marking at the inner spline end of the shaft and also some of the splines look a little bit rubbed, but not bad at all, but could all be a sign of bad bearing and not running straight I'm thinking.
I removed the dust seal from the driveshaft outlet of the transfer box, but I don't see a bearing that I can remove from the outside, is it inside?
Is that piece with the holes in it a bearing?
It's not easy to see in the pic, but there's 2 score marks highlighted, are they a sign of something not running straight?
Also, there a sharp / razor like edge on the bottom semi-circle of the outlet hole highlighted in pic, this suggests the driveshaft isn't running straight and rubbing the surface?
Does the above pics all point to a worn bearing in the transfer box where the driveshafts sit in and if so how do I change these bearings?
