lost my "Death Wobble" virginity

[tacticalloader]

Well that sucks! i will be replacing parts this weekend, as i dont want to do that again. Going 50 on the highway, traffic ahead stopping. I ease onto my breaks and as i approach 35 the violence begins. I upgraded to goodyear 16.5x37 Military radials 3 weeks back, have put 800 miles on them already, first time. My M1031 only has 17k on it. I am surprised to have worn out front end parts already. Going to do king pins and steering stabilizer. Anything else i should check. i should note i am a CUCV virgin and have only had it for about 6 weeks. i have been paying my dues though lol

I havent experienced the Death Wobble... have seen and read several posts about it. Scares the crap out of me.. describe it if you dont mind.

Thanks

Death wobble culprits I start with are:

1. Make sure front tires are balanced
2. check for lose wheel bearings
3. rotors and pads
3. then go to steering and kingpins.

I do not believe any light duty truck should need a steering stabilizer(s) Unless your trying to hide another issue or some cool factor. My M715 has 38" XL's and are fun to balance with the stock rims but when done right drives smooth.

YMMV

At 35mph only when braking or always? If when braking, turn your rotors.

If it's truly 17K, i'd change just the king pin bushings and springs, after you first check what Kevin suggested.

Hydraulic assisted steering cleared up my death wobble

Had this same problem on my 1-ton GMC 2wd, and after days of looking and searching for some phantom front-end problem I discovered----------- it's the disk brakes! Caliper(s) were rusted and hanging up, anti-rattle spring(s) missing or rusted, pads gone bad--- whatever--- look at you front brakes first, you might be surprised what you find.

that just masks it.



IF ANYONE HAS DW CHANGE YOU YOUR KING PIN SPRINGS FIRST AND GO FROM THERE 90% OF DW ON A DANA 60 IS KING PIN SPRINGS.

Ditto, what cucvnut said. Had death wobble, balanced / rotated/ inflated tires, did not fix, then snugged up the front bearings, no fix... then changed the front king pin white bushings and springs, problem solved. I went for an alignment after that and all was already exactly correct. The King pin spring was a good 1/4" to 3/8" shorter, it had 'set' over the 25 years in service. The kit is cheap and you can change them very quickly. Try that first.

Since we're talking rebuild kits, anyone have experience with the one from Sky Manufacturing?

It's supposedly all Spicer parts... Wanted to consult the forum, though.

 

[Cucvnut]

Sky ORD WFO it does not matter where you get the rebuild kit from.

Hey, tacticalloader, welcome to the site, can we get some side pics of your SECM M1031 with the 37's??? Looks like you did a arch cutout over the rears with no lift front or rear? I'm planning installing the 37's on my identical truck and would like to see what you did.

Replaced my kingpin springs and bushings, and also shimmed the spring. No death wobble, even without a steering stabilizer with unbalanced 42" TSL's.

i just want to clear some things up on the dreaded death-wobble, which i have experienced a few times, and due to funds and time have not fixed yet, but will be soon... if you have an M1009, your not going to be a victim of the "Dreaded Death Wobble" we are all talking about... this is something that takes place with M1008, M1010, M1028., and any other variation of the Chevy 5/4 ton CUCV's that have Dana 60 Kingpin frontend... it is usually, but not always, due to worn out kingpin springs and bushings... if your M1009 is experiencing this type of problem, it is probably due to bad/worn brake components, bad balljoints(i believe you have those on M1009s) or bad wheelbearings... hope this helps ...

This was a huge help, thank you very much.

As far as a source for parts, I ordered all my stuff from the www.fwdfactory.com Showed up fast, spicer parts & timkin bearings, good price. They have all the dana 60 parts on hand.

The TMs are obviously the place to start...but I found this link to give a good overview.

Welcome TacticalLoader. I to am new to this site and cucv's. My M1037 had 43,500 miles on it when I bought it. It came from an army reserve unit so I thought it would have been better maintained, not so. I have been slowly but surely doing all the regular maintenance on it. The rear axle shafts had never been off from the factory so the rear drums and brakes had never been inspected. You need to look at everything before you use you truck regularly. Good luck and enjoy your truck. I do mine.
