T series wheel wobble

[ae86 slide]

Car - Ae86

motor / part in question - t series drum rear end

problem - the rear seems to sway when cornering or swerving left to right. Almost like a datsun hicas sort of thing (I would imagine, I've never driven one)

occurs/started when (if applicable)-

personal situation (if applicable)-
This problem is actually in a mates 86, he has been struggling with it for quite a while. The problem has been isolated to the hub/wheel sort of area.
Basically all bushes have been replaced, new shocks, new t3 4 link, new bearings/seals in the diff, wheels changed (to check the wheel wasn't flexing) and even spare axles put in, still the problem is there.

When the car is jacked up the wheel can be wobbled, you can pull and push on the wheel and cause it to tow in and out by maybe 5mm. Not just tyre flex, you can actually see the rim moving.

We are out of ideas and matsuri is around the corner. Has anyone had this sort of problem before?

What did the axle bearings look/feel like? (or you replaced them as well as the diff bearings?) Do the splines sit in the diff center properly?

Have the wheel studs been pressed in right ?

[ae86 slide]

Yes to both of those suggestions, new bearings and the bearings look like they have just been pulled out of the packet.

Wheel studs was one of our theories. Double checked that and even tried different axles with hubs, bearings and wheel studs.

So the movement is between 3 and 6 o'clock? Is it on both sides or just one?

Can you remove the wheel and still do it?

[Gunner]

Either diff shims are rooted, or bearings are out of round. Gueasing its clipped more than one gitter in its time?

Thanks for the suggestions. The movement is 360deg, you can grab left and right or top and bottom and get the movement.

The prob is on both sides but more noticeable on the drivers side.

And with this diff in this car it hasn't met a gutter, but the housing/axles/hubs may have in the previous car (but we have tried different axles).

Today we plan on getting a big length of steel, drill 2 holes with 114.3 spacing, take the wheel off and bolt the steel on and try and pin point where the movement is.

As a comparison, my 86 has the same amount of wheel flex as my mates. So now we are back to square one.

[ae86 slide]

Now we are wondering how much should wheels flex? We have checked on his equips, my p1's and my skylines reverse mesh and all of those wheels had noticeable flex when looking from the back of the car, underneath towards the front. And watching the rim in relation to the chassis rail. I never thought rims could flex (espacially manually pulling and pushing by hand).

I should be able to check tomorrow afternoon if I remember on my T18.
