It is s Southern Car from SC and is now in TN. No rust at all. None

I dunno we will see what I buy when I order the parts. I suppose it depends on what kind of mood I am in at the time.

I will not do an alignment if I only replace the UCA and the bushing on the sway bar. Is this the correct thing to do??

I would get an alignment if the UCA is replaced, simply because the UCA bushing that are in there now may be deformed if they're old, which would mean new, healthy bushings might push it out of alignment a little. Alignment is pretty sensitive. Others may have different opinions; I'm not really the expert here.

But, that would be my advice.

Make sure you order two torsion bar bushings for one side ... there is one on either side of the UCA where it connects to the torsion bar. I don't see any problem with only replacing one UCA and not the other, if the other looks good. When I bought my 240D, the driver's side looked perfect. The passenger side looked like this:

I replaced the bad one and all seems to be well in the UCA department.
