Hmmm... I'm looking at NTB03-046, and it seems to be dated 4-25-03. I would have thought that Nissan would have fixed the issue by the '05 model year, but, I guess not.

 

Did you experience this on your Z?

 

Mine is dated SEP 16 2004.....Applied Vehicles 2003-2004
The '04 models were not out yet as of your 4-25-03 date!

 

Yes, and I had the TSB done, which mostly fixed the problem (although on some roads that appear to not have much of a crown, the car still sometimes drifts just a little to the right).

To be honest, though, the perceived worse turning response to right-hand corners makes this fix a double-edged sword.

 

Do you have the befor and after alignment numbers for the rod change.
I would suspect drift to the right could be reduced by increasing caster on the left side or reducing caster on the right side and that this would affect toe but there is no mention of checking alignment in the TSB before taking corrective action or after.

Camber and caster adjustments were made obsolete by using manufacturing processes that were tight enough that resulted in alignment being in spec at completion. It saves time and money.
