Trying to figure out what is going on

[Rolla]

Now I have posted this on another website so I am going to try and explain my issue better in hopes of some better ideas of what is going on.

The main issue is when reversing my car and turning the wheels I hear a thumping/rubbing coming from the front end of the car it doesn't seem to matter if this is first thing in the morning or after a long drive. It doesn't seem to matter what direction I am turning the sound/feeling is the same. I know it is cold here and that might place a little part in this but won't I experience the same thing going forward and turning? I would really like to try and figure this out without having to take it in. Thanks in the advance.

I know exactly what your talking about, I've had that happen to me everytime i would reverse in my parking lot the first year i owned my car till i gotten new tires and alignment... After the alignment that thumping went away... To me, it felt like either a tire was unevenly worn or like a thump with a slight wiggle coming from the front suspension. I remember feeling this same thing in afew other cars i've owned in the past but nothing was wrong with them at all, alignment was straight... its just the stock setup that some cars have that will produce that effect while reversing with the wheel nearly locked to the left or right.

It's been covered before so this should help: -

1. Clunk in steering at full lock when cold
   
2. Power steering shudder on the Boxster at low speed

Oddly I have experienced a odd bump and dragging/rubbing sound when reversing. It is part of the large scale maintenance I am about to tackle on my car. With my experience in racing and other cars(not Porsches) I associate it with a failing/damaged ball joint. It seems to be that when reversing and that the passenger wheel makes an odd knock and then its like the tire has an incorrect toe and drags a little. I do not notice while driving forward only when reversing bring the car out to the left. I'll post if I find a definite result. HTH
