When replacing a stud on the front wheel of my 95 Legacy I had to grind a small flat on the new stud to get just enough clearance to snake it in. That was a 3 minute task, the rest of the job being 15 minutes if you count removing/replacing the tire.
My 95 2.2 gets the ticking tapping noise roughly 3000 - 5000 miles after an oil change. That works o.k. though because when I change the oil the noise goes away.
Works better than the reminder sticker on the windshield when my wife used to go to Jiffy Scrube.
