Upper control arm bushings?

Hi all,

My Spider is back on the road (yay!). In the process of checking some things out, I noticed the bushings on my upper control arms where they connect to the rest of the suspension are very loose and worn. I'm not ready to dump the time and money into a total suspension rebuild, but I'm thinking these bushings and a loose steering box are probably big factors in the sloppy steering.

I figured as easy as these are to access, and as cheap as they supposedly are, I might as well replace them and get some handling quality back. But I can't find them online to purchase! Am I suppose to replace the whole control arm? Another AlfaBB member posted at one time that the bushings are around $10 a piece, but it was an old post.

Thanks!

Matt

It is common to replace the bushings with the far more robust bushings used on the wishbones. No mods required, available they the normal Alfa suppliers for about $35 . http://classicalfa.com/products/SU04...RODUCTION.html

Loose steering box?

A loose steering box could be a cracked steering box. That could be a disaster in the making. Please inspect the box for cracks or breaks.

Poly bushings are another option. Not as compliant as rubber but more compliant that lower wishbone bushes.

Can you be more specific as to which bushing is very loose and worn? The upper control arm connects at three points: to the body (inner bushing), to the caster arm (caster arm bushing) and to the spindle. The first two bushings are available. The link to the top of the spindle is not replaceable, so if that's what is loose and worn, then yes, you need to replace the whole upper control arm.

Agree. Burman steering boxes don't commonly become loose/sloppy - unless they are cracked, which certainly is a "disaster in the making". Are you sure your play isn't due to worn tie rod ends, or a sloppy idler box?

Sorry, I am referring specifically to the inner bushing on the upper arm. Jay is correct that there is the small caster arm bushing and the spindle ball joint. There is also the caster arm ball joint. Any of those can cause slop but the one that tends to go first is the upper inner bush.

I also concur, don't drive the car again until you determine where the steering slop is coming from. It's not fun when the steering box explodes (ask me how I know...).
