I have around 5,000 miles on my truck so far and love it.

I was coming back from a trip running around 75 mph when the traffic was stopped ahead and I had to really hit the brakes hard. It stopped fine, except there was a little slalom type of movement in the front end while braking. the back end tracked straght. Nothing that required any correction or letting off of the brakes. I did not feel any ABS pulsating, so I don't think it got to that point for the ABS to kick in.

Has anyone had this occur ? If so, any suggestions ?

I did recently put on Fox 2.0 shocks dialed in by Thuren, Thuren's track bar and a set of sulastic spring shackles. I never had to hit the brakes hard before the upgrades, but I don't see how they could be at issue as I see them as upgrades.

Thanks,

Bill

Stock tires?

Might need an alignment...check the toe in/out and caster/camber especially.

Yes, stock tires, BFG Rugged trail, 265 X 70 X 17.

Do different tires create this problem ?

I was thinking about some Dura Grapplers in a 275 X 75 X 17, but don't want to make it worse.

I will get an alignment.

Thanks for the responses.

I experienced a similar thing under hard breaking when traffic stopped. The truck got a little squirrelly. Didn't expect this 8,000 lb+, high center-of-gravity truck to brake like the BMW M3 I used to have.

The way these trucks are, with the short arm 4-link front suspension, they get sort of a "skateboard steering" effect when the chassis leans from side to side. That, coupled with the soft control arm bushings adding to the wheel base changes side-to-side, makes things get a little fishy at speed. Totally normal just part of having a big heavy truck.

Was going to say the same thing Thuren.

We have the same issue when we're calibrating ABS out at Chelsea proving grounds. Perfectly normal as long as you aren't having the rear end wrap around on you.

Thanks for the replies Don and Shibbyutman.

""skateboard steering" effect "..... that describes it exactly.

Like I said, it was not that big of a deal, just wanted to find out if it was normal.

Thanks for your help.

BTW, between Don's trackbar, his Fox springs and the sulastic spring shackles, the ride has really improved on the road. I have had the upgrades on for 3 weeks or so now, and the truck is riding better as time goes by and the parts wear in.
