Rubber bushings are designed to give some compliance as the suspension moves. The eyebolt and upper trunnion bushings twist and with poly they allow the pin to pivot. The tie bar needs some squish which poly doesn't do well. By using rubber in the back you get the compliance but the firmer poly in the front for the braking force resistance.

Exactly as Jim said above.

I have just rebuilt mine to that spec and it has transfomed the cars handling and braking.

Update and a new noise:

Everything is back together and I've put maybe 40 test miles on the car. Definitely feels better, and doesn't crash over the bumps anymore. Brakes feel good as well (Ford discs).

However...

A new noise has arrived. Comes and goes somewhat, but has been persistent after about the first 15 miles I drove. It's a constant pitch with somewhat varying pulsing, a woowoowoowoowoowoowoo sort of thing.

Sometimes it will stop with a quick flick of the steering wheel, and a foot on the brake will stop it as well (as long as the brakes are engaged). I'm feeling some vibration when I can hear the noise.

Thoughts?

More ikely an issue with the brakes or possibly wheel bearings versus suspension which would not be constant and directly tied to road speed or wheel rotation. Is there a difference with a lift foot on the brake pedal? Any pulsing on the pedal? Hopefully those with Ford disc experience will have some ideas.

Either

Live with it

or

Take the new bits off and put them back on again upside down.

I'm thinking it's brakes or bearings/hubs as well. Going to pull the hubs/brakes apart this weekend and check for any rubbing or loose bits.

I suggest you mix and match the parts when you rebuild Drew.

Your woowoowooing sounds bearingish, The Ford kit uses tapered rollers I believe, maybe adjustment required.......

The bearings seem to be set correctly (tapered bearings). Hand tight to where there is no play, then snugged up a little more and secured with the split pin -- as per the instructions.

If I put a tiny bit or pressure on the brake pedal when the sound/vibration is happening, it goes away. Left foot braking while driving and the sound stops. So now I'm wondering if the pads are vibrating somehow.

I am much more sure now that it is not a suspension issue. Going to move this discussion over to the Modified Minors section to see if anyone has experience with this Ford kit.

Try driving round with your brakes EVER SO slightly on.

Yeah, I was dead rude and shouted "EVER SO"

Sorry

Ultimately I got the old Spridget brakes back on and was able to make the tour in time. Need to take a bit of time off from the car to regain my life, then it's time to get back to the disc brake upgrade and the rear suspension.

I will say that the car rode noticeably better, even with just the front end done. No crashing over bumps, and much more controlled. I can only imagine how nice it will be once the rear is done to match.

This is the view out over Douglas Pass in Colorado.

Lovely picture, thanks Drew

Finally back at it! Been one of those summers.

Had some time off today so got out to the shop to work on the rear suspension. I've already got all the parts on hand so I'm hoping to get it all done this weekend. Today I got the right rear suspension apart. All came off fairly simply, other than a few struggles with the front spring hanger pin. Still, got it all apart in a couple hours. Should be able to install it all in the morning and then will tackle the other side.



All new hardware, poly bushes, and rebuilt shocks.

Made good progress today. RH side is installed without issue. LH side is mostly done, just need to attach the new shock. Unfortunately I needed to be able to reuse the 2 bolts that attach the shock to the mounting plate, and one of the bolts is very much buggered. So things are at a standstill until I can get a new one.

Once that's in hand I'll be able to button things up.

All in all, a good day's work then Drew
