Hello

I brought my f430 to the local former service dealer after a major in Chicago. After the major the rear differential was locking up. They flushed and changed the fluid and now it is perfect. They mentioned that the screws on the top of the rear diffuser were torque and will need to be replaced. They mentioned they are titanium. Does anyone have a source or alternative? Funny of they are titanium they should resist getting stripped? Why are these screws so high specified (titanium)
Any suggestions on how to approach Chicago dealer? At least for the rear diff ?
Thanks.

Scott- Titanium is not as strong as steel, it is just lighter. Can think of no reason to put titanium screws in body parts, only titanium in reciprocating parts (connecting rods, etc) or parts where you want to decrease unsprung weight (wheel bolts, etc) and replace heavier steel components. Possibly an exhaust because titanium is lighter and heat resistant enough to work.


Screws were torque makes no sense. Stripped?

Yes. Typing on iPhone getting on a plane.

Dealer suggested screws were over torqued or the wrong size wrench applied and the screws were stripped. I have not seen them but I thought they should be replaced. I checked Ricambi and could not find them.

Thanks.

Separate unrelated question your 575 is November 03 build. I was looking at 2004 575- November 03 build but number 35186 ( last six in vin). Seems odds that the same month would be so far apart.

Scott- 135171 and 135186 are not that far apart and were probably on the assembly line at the same time.

Terry
So this build number would have the upgrades as well?

Thanks

Taz, corrosion pehaps?

David- Stainless steel would be cheaper and tougher.

They are aluminum, not titanium. I have to seriously question anyone who thinks they are titanium for a number of reasons.


I throw them away and install steel. Available at any fastener supplier.



Approach dealer for diff? Why?

Scott- Look at the Assembly Number and you can tell which updates have been done. You can crosscheck Assembly Number with Serial Number in the second list.

Brian- Aluminum screws? Really weird. Wonder why they strip?
