Thanks for that Geeves,
That pic is just one I grabbed from the net that looks similar to my truck, I don't have a current pic of my truck. Mines running 16 inch alloys with tyres a bit under 31inch.
I'll check the shocks next time it's on the hoist to see if it's running originals. I don't have a favourite brand of shock, I've never purchased shocks before. How will I know if they are too stiff or soft? I've got a GoPro camera I could mount under the vehicle looking at the suspension then go for a 100kph drive if that would help.
Yeh I had wondered about some different leaves, I think the hilux guys use falcon ute leaf springs in the rear. Is there some cheap option out there that I could pick up from a wrecker that would give me 5 thinner leaves?
Usage is mainly on road 100kph, some city driving.
Wheel alignment seems ok at the moment, I did it a while back, all the tyres have uniform wear but it's a bit low on the center and outer edges, I don't know how to get it to wear the other bits.
The front IFS has been wound up a bit to help clear the 31"ish tyres. Do you think I'll need to ball joint flip for that? I guess a video of the IFS suspension will show me if I'm hitting the bump stops.
Thanks again for your help Geeves
