My Jackaroo is loaded with 200 to 350 kg. of equipment as it is used for service work. Rather than unload it each night I have taken to jacking it up 150mm under the centre strut as the previous Jack. rear sagged over 3 years. The ride and height have improved but could I be causing any long term damage? Any thoughts welcome.

Hi Steven. I have a rodeo with a similar problem. My ute is a single cab and after I bought it and loaded it with a few tools, it sagged. I looked at Pedders reseting the rear springs, then asked my Holden dealer if it would void the warranty. As it turns out saggy springs in Rodeos are a fault that Holden are aware of, so they had them reset under warranty! (I bet they don't want that to be common knowledge). However that is fine with my normal laod of
tools and gear, but as soon as I put anything extra on, it sags again. When I took it back to Holden they said that I was overloading it, but I put it on a weighbridge and was actually 400kg less than the GVM. It seems strange that the car is given a GVM that it is not capable of handling. Anyway, I went down to Pedders and they offered two solutions. 1. is a Load Ryder which is a horizontal coli spring which only comes into effect when the extra weight flattens your leaf springs.2. is airbags, which you pump up at the servo with the air hose. This way the more pressure you put in, the stiffer your
suspension is. I haven't actually put any of these on. I suspect but don't actually know for sure, that the load ryder may affect the spring action when off roading. So I'll either go for another reset($0 under warranty) or airbags (approx $400). Hope this gives you a few options!
Cheers.

Mark, thanks for the advice. My springs have not sagged, its just that I noticed my new Jac. was higher in the rear when parked next to the old one(both unloaded) so I thought taking the weight off
the springs each night might make a difference, its certainly feels better on the road now and is 15mm. higher than it used to be at the end of the day. Cheers
