rough feeling under truck ??

[storm]

Well I been hammering on the truck pretty good and it seems to be getting worse by the day.
when your just crusing about 40-60 mpg you feel a rough, kind of like somethings out of balance or bad bearing type feel.
I replaced the front shaft with a gilbert still the same. My cv boots were bad so I put in 1 new axels, and 1 new hubs for the heck of it. still doing the same thing changed fluid in t-case/ front diff/ rear, still the same its in the front 1/2 of the truck. I assume t-case or front diff, rotors, wheels are cleaned up and mounted perfect so its not that.

Let me know how to check diff and the t-case
thanks

40-60 mpg

thats some great gas mileage :tup:

does it change any if you turn the wheel slightly? one side or other get better or worse? you could take the front propshaft out and see if it changes too

Ha , Yeah I had alot of beers last night. Seems like it goes away for a monent if it turn the wheel.
guess i will take the shaft out and take a short easy trip and see what happens, I did notice it seems like there is a littke play in the shaft where it exits the t-case , I can move it up/down a few mm. Guess I should be driving the chevelle until I figure this out.

hmmm it does the same thing with the shaft out... However a tech here says time to pull the front diff bad bearings inside...right as opposed to bad bearings outside. time to spend more money.
