For those with strut knowledge:  My main gear was tracking well and tires were wearing evenly.  Recently, I noticed the 4 cap screws on the bottom of the strut were not tight and up along the body were smaller screws were also loose so I tightened them.  Now, the Left Main tire is wearing dramatically on the outside and the plane turns constantly left during taxiing.    My question is: What would that indicate inside the strut?   I hesitate to pull off the strut.   If it is just normal play, I will try to re-align but I'm not sure I want to loosen anything up on the strut at this point until I understand what happened.  Thanks.
