Was the window open?

[lukenemma]

no but thats the sound i get all the time dont sound like any diff of bearing i've heard in the past

[puddlesurfer]

no idea - I guess it could be the LSD slipping but I've never heard of that before

[lukenemma]

The axle code ends ( I think) in 5.
So it might say g245...but I may be wrong. The axle code is on your plate, front bulkhead.

[stormforce]

look on the vin plate for the trans axel code and post it up and we'll tell you if you got lsd fitted or not

cant read the hole of the code but she dose end in a 5 now what would happen if the wrong oil was put in it ? cos i think the last block topped it up with 80w90 i think cos there was a bottle in the truck when i got it and the level is to the top

G145 thanks guys

thats lsd.Just drain the oil and put in some new lsd oil.I can't remember off hand the correct oil type though.Check the diff breather aswell as that may be blocked or siezed.Its a small cylindrical thing on the top of the diff to allow it to breath.If its seized that can cause diff probs

[lukenemma]

so i need to change the oil but what oil do i need seen people say that i need lsd oil is it cheap ? cos i'm broke right now i need me my truck on th road right now bad
