(3) Ball joints, check and replace as needed. To this date, we have never had a DW problem we couldn't fix by using this method.
Stan what's the purpose of that stabilizer/dampener? Do you check all of the steering with the stabilizer connected or disconnected?
And how come I've ran without a stabilizer for well over a year and never had death wobble till my TRE went bad? It's a jk with apparently over 5" of lift bc some guy tried to tell me my frame couldn't be as high as it is, and no control arms to get the caster in spec. Can you explain that?

I use a 15" crescent wrench which opens to 1-7/8" or the control arm nuts and wedge my foot against the frame. I have HF torque wrenches in 3/8" & 1/2". I have a 35 year old California Tool torque wrench that got out of spec when I let a friend borrow it.

Buy a 24" breaker bar. Anchor against the ground like I did here. Now you have 2 hands to lean into/hang on the bolt.

Nah you need to work out, remember I proved that the other day lol or was that Doug lol. One of y'all couldn't bust something loose and I had to put the man hands on it lol. Do the double wrench trick. Most those bolts are 21mm then throw a 24 mm on the other end for more leverage.

That and steering head bearings.

Speed wobbles @ 100mph on a dirt bike in the middle of the desert.... Scariest moment of my life.

I might have even pooped a lil... Just sayin.

Gunner Well it is proper for a race bike so you have quick turn in on the corners. But on the long straights when you wind it up then the geometry is compromised for high speed. Then the damper comes into play. Some of the very best ones are tunable on the fly depending on your part of the track.

Lol so I've heard but with proper geometry you wouldn't have to worry about the dampener like you said.

I've torqued everything on mine before it's not that hard man. Even if you just do German torque specs (good-n-tight) and use big boxed end wrenches, 13/16 fits most of it, or a 21mm. Most the jam nuts I use, not factory stuff, are 1 5/16". That's for my rear control arms, what will be on my new 1 ton steering, and track bar.

Check the holes where the trac bar mounts and see if they are ovaled any and check the heim and bushing on the track bar. What I do to check is have someone in the driver seat with the engine running and turn from 9 o'clock to 3 o'clock back and forth at a decent speed to look for any movement, then I grab the drag link first and see if it resonates thru it. Then the tie rod, and then the track bar. You might feel a clunk on any one of them or all of them. But if it's steering related you won't feel it in the track bar and vise versa. But also if you've got multiple worn out parts they can compound together. Best thing is check everything, then torque everything to spec, and then check it again using the person steering it while you feel and listen for loose or work components. When I mean everything that's control arms and all when it comes to torquing everything.

I ain't in it for the money, it's to build the sport and community.
