Loctite necessary or not for control arm etc.

[thormann]

Hi,

 

To replace drive shaft boots and strut mount, I have disassembled the wheel bearing carrier. The porsche manual says to replace all safety nuts for the control arm, track rod, drive shaft!

 

This is O.K. so far, but I read nothing about using Loctite or similar glues on the threads. What is the advice here, if I replace the nuts anyway? Do I need additional glue?

 

Thanks for any hint!!

The parts list only shows a lock not on the lower wishbone, driveshaft and wheel hub nuts. I personally would use Loctite blue (or equal) on all nuts and bolts that do not have lock nuts - but it is not needed don lock nuts.

Do you need an alignment once undone the spindle?

I would say yes -just to be safe. Chances are something else will move when you remove the spindle.

Thanks for your reply

O.K., but how would you understand the manual? For me it reads like Porsche would not use any glue on the standard nuts!

 

How do you recognize which nuts are safety nuts? Description in the parts list?

I would need to read those specific manual entries.

 

Safety Nuts have a rounded/crimped side with locking material inside.

I would agree.  You only rarely find nothing has moved.

Unfortunately not as per Porsches definition. Here is the M12 nut of the connection control arm / cross member!

 

Porsche calls this nut 99908444501 a safety nut in the part list.

Thormann, the top of the treath part of the M12 nut is oval, not round, as a safety Item.
