Saggy Ass Jeep

[S.Bartfast]

I'm sorry to say it but my Jeep has a Saggy Arse!

I have a 2007 JKU Rubicon and when I bought it it had a 2.5" ARB lift installed. While an ARB lift wouldn't have been my first choice that's what the car came with and I wasn't going to complain. However, I have now noticed that the rear end is surprisingly saggy and the drivers rear tends to bottom out surprisingly often, especially when the sway bar is disconnected. In fact the right rear is so week it's unnerving to drive with the sway-bar disconnected at all. With the front sway connected it levels the car out enough but when the sway-bar's free if the Jeep ends up on a right leaning slope the right drops so much that it's quite disconcerting.

I'm not exactly sure what's causing the problem though. Both the springs and shockers look fine to me and while the car rocks a little more to the right when you shake it on the ground it's not too bad. Does anyone know what I can check for to see if I can find a problem? If the problem is the ARB lift could I get away with just replacing the rear springs or shockers or would I need to replace everything? Also, what 2.5" suspension would people recommend? I run 33" tyres and I'm not really looking to make any drive-line changes as I'm happy with the capability with the 2.5" lift, I'm just concerned about how week the rear end has become.


Thanks for your advice,
Slarti.

BTW, here is a photo on my front suspension:

Personally I think it looks all off center and dodgy as heck but I wouldn't really know. Does anyone know if this suspension looks off?

The springs look tired they should remain parallel not buckling one side. Springs only set a ride height shocks control the movement but if the spring has weakened the weight transfer can cause odd handling characteristics as it becomes overloaded

Adjustable trackbar should centre those springs, if you have a tired rear end, nothing perks it up like a new set of heavier duty springs. this is something that ARB does really well. They have different rate springs for the types of use you are going for. 0-150, 150-300, 300+kg ratings.

The Jeep will naturally want to lean to the right, thats where all the weight is (driver, fuel tank, rear door hinge - thus spare tyre) so a review of your suspension setup is in order by the sounds of it.

Nows probably a good time to find another manufacturer if you want to go that way. It sounds like a few things are on their way out, and might save you money to just revamp the whole lift.

Do you have draws, fridge any thing like that? The dive spring should be taller because of constant load if there is no passanger.
Figure out what you carry and get new springs to suit dont just get heavy duty for the sake of it because it will be rough.. get adjustable arms so you can tilt the diff either way so the springs sit flat. You'll need to do your pan hards too. I dont know about the jk but with the tj you can drill a new hole in the bracket to straighten it up.
