I have a 1987 Corolla.  Very dependable so far.  However, I recently had a new CV boot put on the right side b/c it was broke.  Eversince, when I go on the freeway, it shakes when going faster than 50mph.  If I push the gas pedal down to speed up, it would stop then starts to shake again at 65-70mph.  If I let go of the gas pedal to slow down, it would shake until I get below 50mph.  Some people told me that it's the alignment.  It might be since my front left tire is rather newer than the other 3.  The front left tire got stolen, so I replaced it with the exact rim and newer tire.  Pressure is good in all 4.  What do you guys make of it?  
I know if I take it in for an estimate, they will definitely say that it's the rack & pinion. By the way, the last time the mechanic checked, he said that the rack & pinion is leaking fluid but nothing serious. He put in some Jensen brand power steering fluid and it sorta slow the leak. However, the leak is not bad, I have never seen any drop on the ground, though it looks wet.
What do you guys think?
Any good opinion will be greatful.
Thanks.
