A rapid 2 second shudder

[Pezzer]

Whilst driving on the Hway I get a shudder through the steering like I have gone over the edge lines on the Hway the ones that make a noise. I last for 1/2 seconds the goes for random intervals only to do the same again?

Which one are you in the SWB MAV or the LWB GQ???

[Pezzer]

The SWB Maverick.

[Morton]

could be bearings or a bush is failing, look at the control arm bushes first, then bearings & kingpin bearings

does it always happen at the same speed? every time I get a wobble at 90kph I know I've got bushes wearing out. for me its usually the top panhard bush.

[Pezzer]

No the speed when it happens is varied, and yes it is an auto. I did notice that when towing the Lwb Patrol home the MAverick struggled up hill.

[Pezzer]

Oh yes the bushes are new urethane ones throughout.

[threedogs]

Are all the rims tight. Jack front off the ground and check free play, up and down and sideways

Speed will vary - if the lining is gone, it'll can even attempt to lock up when stationary and cause spluttering like it wants to stall (mine did). Usually worse when it's cold at the onset of the problem.

I would be thinking along the same lines as Scottie hence why I originally asked if it was the Mav or GQ, I just assumed the SWB Mav was manual, sorry I should of asked if it was auto or manual to start with.

[Pezzer]

When its cold the power is down until it has run for 5 mins.

Did it again , went 180 kms and it happened once same as before, just like going over a ripple strip, everything is tight.

Have you got movement in the steering box(bolted onto the chassis under right side mud guard)? With the engine off but key in ignition to unlock the steering lock, I was able to move the steering wheel back and forth and the steering box would make a clunking noise. Fixed this by adjusting the steering box. There is an adjusting screw ontop of the box, just loosen the large jamnut and adjust the screw in the center in 1/8 of a turn increments. I don't know if this wil fix your problem, but I have heard of people fixing their death wobbles by adjusting the steering box.
When you do adjust it, test the steering from lock to lock to ensure that it moves without binding. I'm not 100% sure on what happens within the box when you adjust it, but I'm thinking that adjusting it too much would reduce the acceptable amount of backlash between the gears, causing binding.
