Hey everyone i'm a new member and long time chevy lover! I have a 95 silverado ext cab with a 350 and 5 speed manual trans. At about 55 to 60 mph i have a loud roar inside the cab. No vibrating just a roar and it doesnt do it unless i'm from 55 to 60. Could i be the midshaft bearing? I crawled under and moved the drive shaft around a little, there was maybe 1/4inch of movement. Any ideas would be very helpful.

 

Check the fluid level in your Transmission.

 

Did this just start suddenly or has it came on gradually. Have you done any work to the trk. prior to noise?

 

no i just got the truck. it tuns and drives out great. the noise is just irratating. checked the trans and rearend fluid. its full. and as far as i can tell by turning the driveshaft the universals are in good shape

 

A drive shaft brng should be noticable at most any speed. You might check the ex. to see if it is contacting anything.

 

i'll do that it does have duall exhaust that i need a good reason to make different. thanks for the help buddy

 

could be tires.. one might be wore differently..happened on my 95 when i had stock tires on it.. happened when i rotated tires..transfer case could be stuck in 4wd..but you said no viberation.. doubt that but you never know
