I have a 93 Toyota pickup with a Toyota solid axle up front with marlin high steer. An in the last couple weeks i started getting a death wobble after hitting pot holes. I figured my tre's where trash so I got new ends and just put them on also put on a steering stabilizer. They both didn't help. I then did a knuckle rebuild and
Changed the trunion bearings an it didnt help. Not sure what else to check only other things I can think of is the front shackles and the bushings. Wondering if any one can point me in the right direction?

Matt if the front shackles are loose it will cause death wobble, so will bad tires. make sure your wheel bearings, spacers, and lug nuts are tight too.

How is your Alignment? I have good luck with 1/8" toe in

i checked my shackles they where fine. i just rotated my tires it seemed to help i went for a drive around town, i didnt get a full blown dealth wobble but i can still fell play and im sure in a day or two it will be back to doing it? i just changed out my steering so the alingment is off, but it was doing it before when it was all alingned. i guess i need to cheack the wheel bearing i dont remember if we checked them or not when we did the knuckle rebuild that night/

I dont remember i was not working on your rig man.

Definitely do your alignment

Could also be the caster. Had a wedge put in mine and it did the trick.

What did you set the pre-load on your trunnion bearings at?

Try changeing air pressure in your tires, some times that helps.

What is your caster?

Alignment it.

i have that problem air down to 25psi and check your alignment. i solve mine with an alignment adjustment when i havent gone ram asssist. now even with ram assist i can still notices it but very little notzliceable.

My brother got some of these shackles and it fixed his d/w

You'd be amazed at what the proper toe will do. This was the ticket for my rig when all else failed.

The alignment shop can't align with my beadlocks, and I was astonished to find that after putting on some stock 29" (?) tires I couldn't drive over even 30 mph!! The whole truck was violently shaking! The term death wobble had never been so relevant. I had even drove to the shop moments earlier with my 37s doing 70 on the freeway like it was nothing.

So just the pure mass of our large Rock Crawling tires is enough to cover up a whacked toe adjustment.

After they aligned it I could immediately go any speed I wanted on the lil 29s. I was completely blown away. Truck looked real cute with the stock tires too hhahahaha

im not sure i had a few buddies do the work for me.

ya Ive been driving air down up front to keep it to a minimum but ive tryed all different pressures.

and im going to go get a alignment done and check the caster.

sense im haveing some problems up front already, im going to check my wheel bearing also.

and if those all dont help all grave a set of those shackles

i know i used to get a little wobble.seems the front shackle bolts would loosen off a bit after wheelin.also the steering arm bolts can work loose.i would check those every once in a while.if the come loose it can cause some serious damage.now that i have hydro assist its great.im fully built on 37s and can fly down the highway at any speads with no issues..

NCK4L · « **Reply #12 on:** Aug 22, 2012, 01:08:28 PM »

hydro assist didnt help on my 4runner. it was the rubber bushing in the shackle and leaf spring they were really wore out from flexing . i put new rubber ones in when i built the truck and they were toast after like two months and my shackles were tight . i upgraded to poly urethane and that took care of it. definitly dont count on hydro to fix your wobble

toygasm · « **Reply #13 on:** Aug 22, 2012, 05:53:37 PM »

i re-read my previous post and i guess i kinda said it wrong.wasnt saying hydro assist was the cure.my problem was definately worn shackle bushings/loose shackles.hydro assist just seemed to help with a little tire wobble at higher speeds.when my buddy went to 10"wide rims he would get crazy death wobble and the hydro assist seemed to really help him out.sorry if i confused or mis-lead with my previous post.

How do you go about checking your caster? Never done it. Les schwap I'm sure wouldn't include it in a alignment I figure?

BigMike · « **Reply #15 on:** Aug 23, 2012, 07:10:26 PM »

Caster is not adjustable on solid axle Toyota's. Two quick methods that come to mind are 1) spring perch shims and 2) shorter length front shackles.

Spring shims would be something like this, and would rotate your front pinion up to help get your front drive line out of the rocks and bring your front caster closer to center

Makes sense, thanks big mike. well I'll check it out see if it helps out.

Try glass cleaner. That's always worked well for me for sliding metal into rubber.

dont grease the outside of the bushing or the frame tube. only grease the inside of the bushing and the metal sleave. pop the bushings in the frame tube then tap in the metal sleave with a small hammer.

the first set i installed was a pain in the butt, but after talking to one of davez old imployees he told me the way he does it and its super easy. i can install a set in like 15 min now.

it suppose to be a one man job and it took four guys just to install it..
