Hi Pinno718 and thanks for the comment
If could be binding but the front wheels, which were removed a week after the rears last year, came undone without any undue effort. Personally I always apply copper grease when putting the bolts back in and also on the face of the hub. I also use a torque wrench which my tame mechanic calibrates for me every year.
Impact dizzies are great for undoing things but I wouldn't use one for tightening anything - I generally use a battery powered drill to spin bolts in so their a bit more than finger tight then finish the job with an open ended/ring spanner (for non-critical nuts/bolts) or a torque wrench. 29 years in the military (many of which were in the REME) taught me some tricks
