suspension washers, not shims

Post by dinghyguy » Mon Mar 11, 2019 11:31 pm

Hi All,

Does anyone know if Fiat ever put washers in on the two bolts that hold the lower a arms on to minimize the need for shims? I just took my suspension apart and from what i can tell it had never been apart before and there was a stack of washers on one bolt and a shim on another. The other side had all shims but I think it had been apart. I am suspecting something, but i dont know what.....

And of course do i leave them in there or take them out and put back only shims?

cheers

fiat used washers / full round shims for alignment purposes. When I rebuild front ends I leave them all off. That way I can get the exact adjustment I want. I have run into a few cars that had to have the washers cut to correct the camber. Mainly because the shock tower has been compromised and has been bent inward inducing negative camber. There are a lot of spiders in that situation. The best way is to fix them correctly. But some just want an alignment.

I agree. My 79 had the washers too. When I had it aligned, they removed them. I would prefer full washer-style shims to the shims used by alignment shops.

I use regular shims. But i install them with the open end down. that way they cannot fall out. But when everything is tight that wont happen. I do recommend tightening the cross member bolts regularly anyway

thanks all, I have a mix of washers and shims. I carefully kept them on the right bolt, cleaned them up and put the thick washer closest to the A arm, thinking the thin ones should bear against the crossmember. The shims are outboard of the thick washer. Any reasons why this is not acceptable (except some don't like washers).

It shouldn't matter the order.
