Problem with new kings leafs

Recommended Posts

Just installed some brand new kings leafs in my ute. FOR303SL. I noticed that the back has a nice arch but at the diff they pull upwards then they curve the other way. I'm getting a bit of knocking from them. I took it to a suspension workshop in Geelong and he said the front camber is pretty off making the ends open up and clap. I gave a springworks mob a call in Melbourne and sent the bloke some pics and he said they look fully loaded like theres 400kg in the back and suggested a rebound leaf to pull the camber in better. Already paid for heavy duty performance leafs, don't really want to pay extra to "fix" them. I got straight onto Kings and they can't see any issue with it so I'm kind of stumped at the moment.

 

Has anyone seen this before?

My kings SL leaves look pretty much the same, and I've had a rebound leaf fitted to get rid of axle tramp (which works great)

 

I've got periodic creaking also, worst after it's been sitting around for a while and/or I tighten the axle U-bolts which I do a lot.

Looks like you've got poly bushes, which I believe contribute a bit towards the sound.

 

Give it a couple hundred km and see how it is then... unfortunately the arse end of these utes is still 70's spec so there's no magic fix for these leaf setups

Is yours auto or manual?

Thanks mate.

 

The springworks joint suggested a rebound but that's an extra 600 odd to reset the leafs and put a rebound in, almost double what I paid for the HD leafs!

 

I had poly bushes in the standard leafs and they never creaked. Only carried on a little when the ubolts weren't FT.

 

It's a manual.

Then I wouldn't bother if it's not tramping

 

Interesting RE the bushes, I only swapped from std rubber to poly when I got the kings so was only surmising...

The old springs tramped like crazy.

Haven't put these to the test yet as I'm just a bit worried about how they sit. Had quite a few people say that's how theirs are but a couple mobs say they look way over loaded.

Not the greatest pics from this angle but you can make out the profile of the leaves.

 

If you look closely at the second pic you can see the rebound leaf on top of the pack and where it stops just after the shackle clamp plate.

After fitting the rebound leaf I was out of U-bolt length* so I removed the baby leaf right on the bottom, don't think it makes a heap of difference.

*seems BS as there's plenty of thread hanging out but those poly bushes compress to the sh*thouse, if I clamped the top and bottom plates with a big arse G-clamp I may be able to fit the small leaf back on.

 

The mods on the bottom plates are angles I welded on to stop the warping when tightening U-bolts for the millionth time, there isn't a lot of strength on the inner edge when standard and decent torque distorts them as you can see in OP's pics above.

Thanks legend. Yours definitely look more "together" if that makes sense and with better camber. Probably a product of that rebound leaf.

 

Did you use those black crush plate washers when you got the leafs? I didn't install them in mine, wasn't even sure where to put them exactly! Did you put grease between the poly pads and leafs?

 

Sorry for bugging you mate, just trying to work out what is wrong with mine as it's looking pretty similar to yours!

Everyone is saying it's normal haha It's just the creaking/clunking I can't get my head around!

Agreed. I lurk too much, have for years until I bought one and only think to post when it's pi$$ing me off haha

So I got Suspension City to have a good look over it and identified there wasn't enough grease in the front eye bushes. They slapped some in and off she went. Awesome blokes to deal with too, so helpful and quick. Did it on the spot. They also mentioned that the springs winding up like that were normal! Bugger me.

 

I'm getting the odd knock here and there when slow turning. Buggered if I know what it is!

 

Thanks all for the help!

might be your exhaust hitting your suspension or something, then? hard to guess at the back of a ute as there's not much really to "bump" about

it comes from the rear left predominantly , might be just a quirk of the car, it's been happening for the whole 8 months since I bought it. Naturally I didn't notice it when I test drove it as I had rose tinted glasses from that turbo whistle 😂

Update on this. Turned out to be the gears and pins inside the LSD being super slack, there was a tonne of play. The clutches were surprisingly good. New unit in and all good now, not one clunk/knock in the back and feels super tight. Shout out to Mobile Diff Repairs in Dandenong.

 

Do have a knock though putting the car into reverse and changing from 1st to 2nd, sometimes 2nd to 3rd. Have a feeling the lowered leafs have thrown out the pinion angle or tailshaft making the centre bearing bump because of the flex in the shaft. 

 

What have you guys done to fix this?
