this is my 98 half ton with 201,000 miles.

I don't have a g80 on my truck but damn that would make me think somethin is wrong

[eldreder]

yeah, i was thinking the same. i dont see how that could be anything but bad

[foghorn23]

I couldn't tell completely from the video, but is it happening on take off? (looked like it on vid) I would think the g80 would be more likely to create a vibration issue in cornering (it didn't appear like you were cornering when it did it)

[eldreder]

yes, it was on take off. it didn't do it cornering, but i wasn't on the gas through corners either if that makes a difference.

[mawint]

Mine will hop if I slide the back end and it doesn't have enough speed in the corner. It doesn't do it on takeoff though.

junkyard time?

[herm0016]

when was the fluid changed last?

[eldreder]

i haven't changed the fluid in the 20,000 miles i've owned it. I plan on pulling the cover in the next couple weeks and changing the fluid then.

 

Also, when i pulled one of the wheels there was a "yukon Gear and Axle" sticker on the left rear hub. i know they make diffs and such, but i have no idea why that sticker is on there or if its been rebuilt with their parts or what not.

is it in 4wd ??

 

 

i just reread it ,,

 

almost sounds like the t case chain is jumping the sprockets

 

maybe im on glue ,and the older trucks may have a different t case than newer ones ,i cant remember

 

thats not your t case lol,i listened to it again

[grampadirt]

Little more info on the truck please...long bed,short bed,4x4,2wd?

[eldreder]

its a 1998 extended cab shortbed vortec 5.7L 4x4 z71 with 201,000 on the clock

[grampadirt]

Does it have a two piece driveshaft?The reason I ask this is the vibration acts like a carrier bearing has gone south...

[Stevens03]

That doesn't seem like the locker to me either.

[GasHog369]

IMO dont wait a couple weeks to get in there... or if you must, dont drive the truck in the mean time. You might be hurting it everytime you are taking off like that.

It seems to me something is binding when you are taking off and finally releasing when rolling..
