I had the joints cleaned & put back together properly, no more problems
So, even if the boots look good, look inside.
Or it could be your brakes, but I suggest all Xi owners check for missing grease on the under the inner boots
I was lucky & got it before any damage was done to the axles.
The inners are known to leak on the inboard side of the inner boot. the clamp isnt tight enough or something and it will seep grease out.
