98 s10 blazer chuggling sound/vibrating

[thebartolac]

Hello all, Andrew here, new to the forums, I have a 98 S 10 Blazer 4x4 and within the past 300 miles have been noticing two things, first was the vibrating i felt in the drivers side of the vehicle, it started only on the highway when i was doing 70+, now I can feel it at 30+, my friends say they dont feel it on the passenger side, I have yet to ride on the passanger side to see for myself. I feel it with my foot on the gas pedal or if there on the floor (dunno if that makes a difference)

also the loud not so nice sounding purr, or more roar when im idling or going very very very slow (10 and under) any comments that may lead to me either being able to resolve or anything would be appreicated, pray its not expensive either cause im working the night shift full time just to pay tuition :x

Welcome to AF on your first post.
It is hard to say without looking at it.
But any vibration needs checked out soon.
As it may not be safe to drive.
Vibration at 60-70 may be in tires and wheels.
Bad tire or out of balance or lose wheel.
If you can not see/find anything have a good repair shop check it out as soon as you can.
Good Luck and let us know how it goes.

Hard to get what you are saying there in the second paragraph, but if you are saying that the engine makes a loud roaring sound at speeds under 10mph, that is just your fan clutch engaging which is normal. The warmer the outside temperature, the more it engages (and roars).
