    Porsche 993
  1. Recently i had my p993 left inboard cv boot replaced, after that repair the car vibrate (not actually vibrate, just like the axle was bent but it wasn't , i think it because that the 6 bolts are going to loose that make the car run like with a bent axle, and i'm still don't know what problem that make the 6 bolts llosening) at that side of the axle. On the way home, the axle was loose totally from the stub axle and the mechanic tightened the 6 bolts again. After the second tightening, the car vibrate again and the axle loose from the stub axle again even though the 6 bolts had been tightened by another mechanic from another workshop, and after the third tightening the car still vibrated and on the way home, the axle was loose again for the third times then tightened again for the fourth times with 6 longer bolts in order to get home. I got home at last without knowing the car still vibrate or not because i run the car home very very slowly. And i haven't checked the car now, and i am going to disassemble the axle again trying to see what parts need to be replaced and try to figure out what problem that make the 6 bolts always loosening and what problem that make the car vibrate. What could be the problem ? Wrong method of tightening ? Wrong bearing assembling [the bearing was disassemble in order to replace the cv boot] ? And could the stub axle be bent after three times loose from the inboard stub axle ? Before i replaced the cv boot, the axle is in very good condition as from the factory, never been repaired/disassembled. Thank you very much for any help or suggestion.
  2. Is it ok to replace an OEM Porsche 993 fuel pump with an aftermarket such Aeromotive or Walbro ? Does anybody have the specification of the Bosch Fuel Pump # 0 580 464 058 ? Thank you.
