well it wasn't the wheel bearing although it had all the symptoms. I pulled the old bearing/hub off and there was grease all over the place but there was absolutely no play.

its a speed consistent hum like a mud terrain makes but not nearly as loud. I think it could be the rear axle, prob blew the 7.5 already lol

Gonna try to get it up in the air tomorrow and have someone hit the gas and try to pin point the noise.

 

your drive shaft rubbing on anything?

 

nope. anything it could rub on was ripped off already haha

 

maybe your rear wheel bearings

 

could very well be. I'll try to find the source of the noise tomorrow. just need another person to be in charge of teh throttle

 

wish i had another set of wheels/tires to test too might just be my ****ty tires

 

a center block will work

 

you mean cinder block? might be too heavy lol

 

ya one of those too and you can set it if you know what your doing....just sayin... don't be a P***Y

 

 

touche

 

i had this issue once then i rotated my tires and the hum was fixed, then it did it again and i was in need of new tires. It might just be your tires are worn down to that point where they make that noise.

 

gonna rotate them again today and see what happens. they're pretty bad lol they have cracks in them and crap from sitting for 7 months

 

Its gonna blow up. lol.
nah, sounds like tires.

 

wasn't the tires. its definitely something in the rear. i'm not worried about it now anyway

 

Cause its gonna blow!

 

I would bet on tires or rear bearings for sure. Just because you rotated them doesn't mean that will fix it. Especially if it's all/more than one/or one is just constantly making the same noise regardless of where it's mounted.

 

nobody said rotating the tires would fix it, it would just move the noise. didn't have time to check the bearings or have the truck completely up in the air. If its a bearing im not replacing it, ill buy an 8.8 and rebuild the whole thing lol

 

i was gonna say , could be rear bearings if they are humming ,

 

put on jack stand. start truck. put in gear 1 or 2 listen for noise. prolly the lill 7.5 get a 8.8

 

Mmmmmm 8.8 FTW
