my 91 blazer is having some problem like that. when i have it in gear, theres a tick or whatever in the steering column. it does this whenever it is in gear. i don't know what it is or whatever. im not having any problems driving it, it just gets annoying after awhile. it does it every like 5-10 seconds.
If it flies it dies
