wine when getting towed today

[adamforsythe]

Hello,
Well my '86 Blazer finally made it to the shop today to get the front seal fixed. One thing that I did noticed while getting towed there by my step dad is my truck was making a wining sound. Everything was in "N". The truck was running so that I could steer and brake.
What was the wininmg sound?
Thanks
Adam

Both tranny in neutral, and t case in neutral? Front hubs "free"?

Could be your rear diff...

The engine was running? Could be a lot of things. Belts, blower motor, PS pump. I think we need more specifics.

The hubs are Auto. EVERYTHING was in neutral. This is not a blown motor (I wish it was).

I think 6.2 meant the blower for the heater/ac lol
