Just wondering if when you are crusing at about 55-70 at a constant speed (like with the cruise on) you get a rumbiling sound that goes up and down in pitch... wooooom wooooom wooooom.... Almost sounds like the prop noise from a turbo prop plane. I can almost feel it in the seat also. Exhaust?

[Jeepin Jason]

not that I've noticed. :dunno:

[Hoofmann]

Not really. Could be your tires?

I'm wondering if some air leaked out of the tires over the winter... It is a 06 left over. Thanks!

Next question. My truck didn't come with the block heater cord to plug in in the winter. The Stealer Ship gave me one at the low price of $55 (for what pretty much a 2' extension cord) where does it plug into. I crawled around under the truck for a min and didn't see the plug in. Should be orange with a steel nut that you turn by hand. It looks like the nut you use to hook you CB antenna into the back of the radio but bigger.

I wouldn't know, mine came installed. I could check for ya tomorrow morn.

From the sounds of it you just have to plug it directly into the heater. On my truck the heater is located right below the turbo on the block. On your if it is in the same place it will be kind of behid the turbo since your turbo is mounted alot lower.

yeah I found it.. Thanks!

Have you changed the exhaust? Sometimes removing the cat or changing the exhaust can cause things like this.

[XJ_FIREFIGHTER]

Nope... Truck is stock... Just got it Saturday. Seems to have gone away. Wonder if it was somthing just seating in.

[Hoofmann]

what year is yours?

[XJ_FIREFIGHTER]

[Hoofmann]

yeah it could have just been a break-in kinda thing
