DEATH WOBBLE

The lil'Zuk has double shackles on the front - but it also has death wobble. As you can see from the photo, there's a significant amount of side to side movement even just turning the wheels.

So I've welded a brace across the 2 long shackles. Now that play is gone!

The Zuk is so light it wasn't able to droop the top shackle down, so I also welded it to the frame so it can't move at all.



The top of these 2 shackles are from an XJ, so buddy kindly gave me a couple out of his bone yard to swap out.

Also,  the steering stabilizer was leaking under the boot, so I got that swapped out.

I also did a laser alignment, which showed it to be toe-ing in slightly. So that got adjusted.

Previously the only way to stop the death wobble at low speeds was to air up to 40PSI, which is almost double what is recommended. Even then, I'd get it occasionally from 0 to 20 km/h.

Now with the new shock and the replacement shackle, I was able to air down to 25PSI without any death wobble!
Driving over off camber/diagonal rail tracks was no problem too :)

Now I'm sure the steering stabilizer is probably still masking something as there's a slight steering wheel shake at all speeds, but that could be tire balancing. So I plan to throw some BB gun beads in there, and put the Zuk on stands to check wheel straightness.

Thing rides like a Cadillac now with the tires at the correct pressure :)
