After talking to any one that would listen about the Jacks front axles popping off the circlips I have finally found the answers.Nobody knows or wants to know.
The blokes at Off Road Equipment have been helpful in trying to find out why this would happen,it was thought that the new shockies had allowed the wheels to twist slightly,however this has been cancelled out by Ride Pro and Overlander suspensions.
Further consultations with Holden still have not helped,it seems this problem is insignificant in the world of 4wds.General consensus is that the original circlips were stretched and have slipped off the hub.
This weekend i will take to the hills again to see if the new circlips hold. BTY I have just put Toyo 235/85/16 tyres on the Jack, an instant 20mm lift.

Terryterryfied ? yep, lets do it again

Hi Terry,

How much extra travel do the shocks allow? If the circlips were stretched because the shocks allowed too much travel, then the place you bought them from iand the shock manufacturer is negligent. However, because the dealer changed them under warranty instead of arguing that the shocks caused the problem, I tend to think that they may have already been stuffed before the shocks went on.

Just be wary that with those tyres, your Jack is now technically illegal and can be slapped with an unroadworthy sticker. The maximum increase in diameter allowed in most if not all states is only 15mm. 235/85 tyres are an increase of around 56mm in diameter over the 245/70 tyres. The maximum you can go without getting an engineers certificate is 255/70, which gives you a crappy lift of 7mm.

Can also have implications if you make an insurance claim.

PS ... I personally think that 245/70 are a dumb tyre size for the Jack and they should at least be a 265/70 like Pajero and 90 series Prados.

Savvas, I spoke to the licensing technical department in Perth and they did not see any problems with the 235/85 on the jack.I personally have some reservations and will talk to them again.

Savvas,where did your information for the tyre sizes come from? I still cannot get a definative answer from the vehicle licensing centres, probably to hard to find the answer.Rick Blaine from this website said when the holden team were racing jackaroos they used a 7.50R/16 tyre,4mm different than the 235/85/16.
It is a pain when you cannot get simple answers to ordinary questions,thanks.

The link below points to a NSW info sheet about this rule. It is a national one as it is covered by ADR24. In the past you were able to download the ADR's from the federal Department of Transport website, but know you have to buy the CD-ROM.

Click here for the NSW guideline.

PS ... I saw the 7.50R16's for myself on the Holden Rally Team Jackaroo's at the Sydney 4WD Show at Darling Harbour. Not sure if it was 2002 or 2003.

They had non-standard alloy rims on them, so they may well have been 6" wide or less. I'm fairly certain they would have had engineer's certificates for a number of mods including the tyre size change.
