Death Wobble

[85_Ranger4x4]

40-45 I try to maintain 45 front and rear.
should I be at 60 like the F250?

I know guys used to run 40 in them in Ram 2500's when not hauling/towing because they didn't like the ride at the door sticker tire pressure.

Personally I run 30 in my load range C's.

That's way too much pressure unless you are hauling a heavy load.

Usually, even with an upgraded tire, the pressure recommendstion on the door jam will work. I have load C tires on the 2011, and the recommended 35 psi would have worked but running the math said 36 was best to keep the load capacity around what the OEM setup was.

Now, on the 2019, I have two different sets of pressure, depending on what tires are on the truck. The 115 load tires stay at the OEM 30 psi and the load E mud tires need 38 psi.

I also found, at least with the BFG KO2 tires on the 2011, if the tire pressure is too high, the truck doesn't track straight and needs constant correction. Dropping it down to the right pressure fixes that problem. Not all tires do that, but is an example of why too high of a tire pressure can cause drivability issues.

you dont have classic death wobble.

if you ever experience actual death wobble ..... you will know this is not that.

you need a solid front axle for death wobble.




your rear axle is most likely bent....or your frame is broken. or both. surprised this was not found by alignment guy with these given complaints.

if it is toe in or toe out past a certain point with a solid rear axle ..... even riding one side in the paint of lanes when the roads are wet will send you in the left right death wiggle.

what really sux is tires can develop radial pull if the axle is bent bad in short order and when rotated will make it worse.

death wiggle is usually a result of a tweaked rear axle. it may not be the problem but i would start measuring there.

and since you said around 60mph, that sounds like an out of balance issue. dw can start at anytime over 30 and is as above described. its not fun and can be scary as anything sicne you ahve zero control of steering anymore
