Posotive Rear Camber

[rangemsr]

Still got noticable posotive rear camber on my Syncro 16. I've adjusted some of it out and happy to live with it now, just cannot work out why it's still posotive and it's annoying the 'engineering' part of my brain. Is this common? Any ideas or theories most welcome....

Outer bolts was were virtualy at bottom of the vertical slots, I assume the've been like this since new as bolts were seized solid. Sawed them off and replaplaced the outer bushes and all 4 bolts (lots of copper slip!). Actual bushes all appeared absolutely fine and solid so only replaced outer hacksawed ones. Moved adjustment up to up the top of the slots. This has probably taken half the camber out, but it's still noticably posotive.

- Virtualy the same both sides, so I assume not impact damage
- 92 Syncro 16" 2.1 DJ with spare wheel carier
- Suspension apears completly stock with normal ride height, however does look a litlle low at front compared to back when unladen, despite new front springs.
- Rear Springs have 2 green stripes
- OEM looking Rubbery pad above spring
- OEM looking cast thin alloy shim at bottom of spring. Has recess for spring end and three radial raised areas underneath.
- No evidence of any tinkering with the van
- No obvious damage or corrosion to trailing arms

cheers

cant explain the positive camber but if your sure there is no damage see if a set of baxters camber shims will work the other way around?????

Tar for info on camber shims, looked them up and they would probably sort out the issue. Probably after the summer now, as I need the van on the road.

I also still feel the need to try and work out what's 'out' first. Any one seen this before?

cheers

think a pic of just how it looks would be best?

I take it that it is on the road, has been moved from where it was dropped off the jacks and does have an engine in?

You worked on front suspension once. Camo ex finish army ambulance with a very big ugly SCA roof.

Driven it around a bit and it appears to have settled down to normal height. Always had posotive camber since I bought it ( looks like my pinzgauer did!), tyres worn a bit but drives well albeit no sports car.

Fag packet calc' with empty tank and bolts at the top of the sliders equated to about a degree posotive, will measure properly tonight.

I was lazy and didn't change the inner bushes, but they looked good and the outer ones were very solid and central (plus it's much harder to change inner ones with arms in situ'). When you work out the maths they have to be way off centre to cause a lot of camber change. Maybee I'll have to change them just to see ...

Inner bushes control tracking, outers do camber.
I doubt if it will do anything by changing the inner bushes.
As noted, a few people have bought our camber correction shims (originally designed for lowered vans) and fitted them upside down to overcome the positive camber effect you get when you raise a syncro.
I'm fairly confident that if you fit them it will put you back into the adjustable range on the factory camber adjusters.

Any idea what angle change these shims make (or the approx thick/thin edge measurements and I can work it out) ?

Interesting looking at how swinging arms are fabricated. Visually they look none handed. Only difference appears to be which side you weld on the spring plate and where you weld on the shock mount. Food for thought ...

Before I go fitting shims here's a theory from across the water:

Bearing housings are angled. Someone has done some job and has put them back on swapped over and upside down.

Kinda matches up with what i can see. 16 housing is different than a 14. If anyone with a 16 is willing to have a quick peek under it, then please let me know...

The bearing housings are the same on both sides and if you fit them upside down you wont be able to fit the brake back plates correctly.

Does this apply to a 16incher too? On vagcat there's no Syncro 16 specific drawing. The housing on my van looks nothing like the drawing there. The flange ( where the brake backing plate bolts on to) is rectangular, With possibly 4 or 6 bolt threads coming through it in a oval symetrical patern.

According to ETKA part number 251 501 253 D is the only bearing housing listed for a 16" and is unique to a 16" so they are not handed. I have a drawing somewhere of what they look like and Im trying to locate it

See the lump on the top of the bearing housing, think it's for the ABS sensor. On my van than that lump is on the bottom. Arggg....

Would make sense for production.

Take it, body is good and no signs of welding rear sill/outer cross member areas?

Body very solid. No welding anywhere. After talking to german syncro 16" owners I'm 99.9% sure it's just that someone has put the castings on upside down (probably finish army when replacing rear wheel bearings). No rush now I know what it is. I'll flip them over next time I do the rear brakes, unless I sell the whole van first!
