when the roads are snow covered i hit my brakes and the tires lockup on the snow and i slide like normal. but sometimes when i hit the brakes i get this bad grinding sound. almost sounds just like when you drive on a rubble strip on the side of the road. and almost sounds like its more on the drivers side but i cant be sure. what can this be? im running 6.5" springs and 2" spacers with rugged ridge crossover steering. what could this be?

 

dude mine does the same thing, I gave up trying to figure out what it was
I always wondered if it was a vibration from the calipers, or if it was the brakes locking up and releasing rapidly or something...

 

idk either

 

I always thought of it as more of a popping not a grinding...
now I'm gonna go slide around and see if i can't figure it out haha
we got about 2 1/2 feet of snow in like 5 hours so eh...

 

lol yea we had a huge storm a few weeks ago and this past friday it got up to 50* and then on sunday we got pounded with another huge storm. gotta love michigan

 

Do you have ABS?

 

haha it did that same thing here.
gotta love el nino's ***** of a sister

 

I think he would know if this was ABS

 

Idk if could happen but maybe your front axle shaft is grinding in the housing. Or your tires are rubbing hardcore

 

lol no abs and tires are far from rubbing

 

Could be, but never hurts to ask!!!

 

DUDE! I think I figured it out!
You have an Aussie locker in your D30 rite? I have a lock rite in mine...
I think it's the locker ratcheting, mine only makes the sound when the passenger side tire locks up , If both tires lock, no sound.
So my thought was, one axle brake locked, the other isn't, would make the locker ratchet rapidly making a grinding/popping sound...
It's just a guess, but that's only thing I could come up with, I've been dwelling on it since yesterday haha..

 

if you guys have lunchbox lockers up front then thats what it is. mine does the same thing and it sounds like death sometimes

 

I think ur right. cuz I do have an aussie. thanks tanner. appreciate it
