As I said earlier, it looks to me like the outside edge and tyre wall has been the contact patch when under high speed cornering due to a lack of give in the rear springs. Its not a constant toe drag as you'd experience on a poorly aligned front end, but intermittent wear as a result of cornering. |

It wouldn't take much... and might be barely noticeable to the eye. It wasn't an unusual problem to have with a 9inch axle housing in the old days... which produced the same outcomes. I've had many leaf spring Falcons.... Lowered, lifted, soft & hard set-ups... BW, Dana & 9in... I've done fairly high Ks in All of them... All but one looked after the rear tyres, and the one that didn't was bent back in the middle and did what yours is doing. Might just pay to double check it again !?? D

Gothefalcon, if the axle was bent, would you expect both sides to be scrubbed or just the bent side? If both, would you expect it to be even wear or uneven, side to side?
Here's the drivers side tyre; ![]() not quite as bad as the passenger side.

It's all just theory untill you measure things accurately and find an issue or not. My 9in housing was only out by mm... I replaced it and it fixed it for me. No suspension changes required. As I said, apart from that one housing on that car, my rear tyres have always worn evenly. You've got something out of whack.... I can't see stiffer springs causing that. For the last 6-9yrs I've had a stock BA wagon... so fairly soft rear springs... and my BF2 AWD Wagon which has 1tonner Ute springs with an extra intermediate leaf... so fairly stiff. The BA has normal Wagon body roll at the rear... the BF2 hardly rolls at all... tyre wear on both is even. D

I'm no expert but I wonder if the super stiff springs has bent the axle upwards over time?
Because if it was from being overloaded then the axle would be bent downwards, causing the inside of the tyres to wear?

OP. like what's been mentioned, you need to measure up the rear axle - better still, get a thrust alignment from a suspension place, so you can see where the front and rear ends are at. Be interesting to see the alignment figures from when all the suspension work was done. |

Well........., I took the bullbar off and took it to a tyre place for a wheel alignment. The guy told me the alignment was out by 6mm!! I don't understand how it could be that bad and still track straight but it did. Once I got it back it transformed the car. All the twitchyness went away, the odd tyre wear seems to have stopped and it even felt pretty good on dirt roads even with the stiff suspension. The rear is still too stiff IMO and the rear wants to step out a little too easily but all in all it's not too bad if you don't push it hard.
The bullbar is back on it now to see if it is going to affect the wear of the rear tyres but so far it's all good. I'm going to use it to pull my Delica to the diesel mechanic next week on a car trailer so we'll see how good this towing set up really is. Cheers Bushbasher

Yep sounds like it will smooth out with a load.

Just put a post 'somewhere' ( a barely computer literate newbie here ) regarding the BF wagon I have and possible suspension improvements.
This thread has proved invaluable and I thank you one and all for sharing this as I feel much more able to approach my car issues with at least a bit better understanding of what I am doing and what to look for. ![]() Anyone ever fit a sway bar in the rear of a Falcon wagon? Good bad or save my money and busted knuckles? Do the front with a stiffer bar as well? BTW. With the spare mounted right side rear compartment due to the LPG tank taking its place underneath apparently it is normal to see more sag in the right rear leaf spring. Pedders put an extra leaf in both but a slightly stiffer one in the right side. Wife did a great job catching a tailslide in the wet when it stepped out (its done it to me too) and I decided better tyres were needed and that improved things a lot. Seems modern tyre compounds go hard and become less grippy quite fast now with plenty of tread remaining - synthetic (non)rubber I guess. |

Welcome to the forums mate, there's plenty to learn around here if you take a look .
As for suspension sag, never heard of that before and I've been driving dual fuel Ford wagons since 06. Our last AU went 450k without sagging on the drivers side and is still going strong as a shearers bus last I heard. You certainly don't need an extra leaf in the rear just to carry a spare and gas tank. Mine is set up like that because it was built up to pull a 25' caravan before we bought it. I'd like to remove the extra springs but the missus won't hear of it, and it's her car not mine. If yours is a series III like ours it has Dynamic Stability Control so will pull the car straight if it senses a slide, otherwise your cars tendency to want to slide is because of those extra leaves in the rear springs making the rear too stiff compared to the front.

6mm out at the front?? Does he mean he had to add or subtract 6mm of shims ??

I would also recommend lowering your tyre pressures in the rear, I personally run 26psi in leaf spring falcons with no load. Up to 30 on long highway trips and naturally higher again if it is actually carrying something. From memory none of the egas Falcons got tc or esp at all?
