ive heard this term used on here and im just wondering what its refearing tooo
DW is when the front end on a straight axle rig jumps up and down.
the term refers to violent shaking of the front tires at around 25 mph. and it doesnt go away till you come to a complete stop. could be many things causing it
You don't know what it is really until it happens, but it's scary.
why the hell would this happen
worn steering parts, ball joints, kingpins. pretty much any frontend component
Scary enough to make a grown man soil himself...
Most common with D60 front ends, mostly when the king pin springs lose a bit of their ability to preload the bushings. A bump at moderate speeds causes the bushing to momentarily unseat from the kingpin. Once that happens the wheels lose stabilty and start to oscillate side to side and up and down.
I've heard of similar 'shake' or 'wobble' with the balljoint front ends, but this is usually when more than one steering component is very worn. DW can occur on a very fresh D60, mostly because even new king pin springs and bushings weren't ever designed with 40"+ tires in mind.
You are right! I built my 60 up all new and went for a test run and DW @ 40 mph So I had to shim it a bit and works great for now.
what did you shim to get yours to work my front end is all new rebuilt nothing used or reused everything new on the D60 but I havge serious death wobble.
I have DW myself right now and am about a day away from fixing it for a long time. The major culprit of DW is a misadjusted or worn steering gear box and other front end components that are worn can also cause it or contribute to it. In my case everything has checked out good except for the play i found in my steering gear box so i'm in the middle of rebuilding another gear box as we speak. I will let you guys all know if this fix's my DW and soon after i'm going to do a write up about how to rebuild a power steering gear box.
Because god hates you
Take your king pin caps off, get new springs (10$) and some 9/16 thin washers and put 1 on each side then drive it. If it still does it then add 2 .....that is what I had to do and havent had dw for 4 months now and I drive it everyday. I know it will happen again soon I feel it
you see people talking about DW in the Dana 60 but how many have experienced with a Dana 44? Just happened to me today.
I run a pair of 1/2" fender washers as shims under each cap, haven't had DW since i did that 2 1/2 years ago. I've put ~20,000 miles on since then.
If this is so common why are we using the dana 60?
You mean like on top of the spring???
A new steering stabilizer fixed that on mine....
yea can be caused by a worn or no steering stabilizer
and unbalanced tires can contribute to it
I've had death wobble on a few rigs before, mainly Dana 60 front trucks. Various causes I have had included larger unbalanced tires, worn drag link ends and loose steering box bolts, and I am currently combatting a it in my crew cab... has a bad stabilizer and I probably need to replace and shim king pins as previously mentioned.
this is crazy I was just trying to solve that problem last night it looks as if my preload bushings are worn. but you guys are saying that the spings may be bad too? how can I tell how tall should they be?
Why would a fresly redone d60 with all new parts do it that makes no sence to me. If all the parts are new there should be plenty of pressure to hold everything down.
