Hi all
I have lifted back the IRS into the car. All is well except that I cannot get the radius arms up to the right place to fix them to the car.
They end up about 1 inch to far backwards. See pictures (the car stands on its wheels). What am I missing?
thanks

Is the full weight of the car on the suspension? It looks like there is a lot of droop in the position of the outer hubs and this would cause the radius arms to be pulled away from the anchor points.

There is a surprising amount of flex in the main suspension mounts, you can rock the suspension forward a bit. Other thing I do is coat the cups on the body in antiselze and simply jack the arms up and the mount will slip up and over the cup on the body.

 

Hi
Thanks for the answers, I think I will try with some force. The right side is a bit close, will start there.
The full weight is on the wheels but the car is empty inside (engine and transmission still in) so a bit less weight than normally. Should not make that much difference I guess…
Still, I suspect that the car is sitting a bit higher than it should, see picture…? Maybe I assembled the spring/shocks incorrectly?

 

I'm going way out on a limb here and say that your rear stance seems much too high to me. Your positive camber is noticeable and there is a lot of daylight from the top of the tire to the wheel arch. Maybe 2"+. Rear camber should be 3/4* -/+ 1/4* of NEGATIVE camber at normal ride height. Someone with much more experience than me will chime in here and give an opinion.

Brute force almost always gets the job done, but sometimes it creates another job.

I wouldn't worry about the height now. If you've had the car jacked up the wheels swing inwards. As you lower the car the tires contact the ground and can't move outward because they are not rolling. If you had put two pieces of plexiglass under the tire with grease in-between so the pieces can slide you'd find the car would drop about another 2".

 

Thank you for supporting my opinion Jagboi64. I agree with your reasoning as to why the suspension is quite high in the rear (and maybe the front too). Setting the wheels down on blocks with a floor jack will create what I see in the pictures. Had slip plates or greased plexiglass been used, the suspension would be very near ride height...but they weren't used, I'm guessing. So the suspension is as you see it. No matter how it got to where it is, I think it is adding to the difficulty connecting the radius arm, I'm just saying....

I'm sorry I talked around you mlindblom, I was just offering some input that I believe has merit. I could very well be wrong as to why you are having trouble.

I learned the hard way when I did a restoration and thought the car was way too high.

For getting the arm on, it might help to have a small jack under the shock/control arm and take some weight up and compress the spring a bit. The will bring up the hub and make it easier to get the rubber mount onto the cup on the body.

 

Hi all
Thanks for all the tips. I managed to force in the radius arms into the sockets. I will try out with sliding plates some time to see if it sinks. If not... I anyway have to remove it completely again in a while. Now I only mounted it to be able to move the car around. Then I can figure out if I mounted the spring/shocks wrong. Picture how it looked before I ripped the car apart. There I think it was right.
