Ah, appointment changes everything about my opinion. I agree, find a more specialized shop. In a prior life, I was service writer and worked on and around cars. My advice I always give to people when they ask for a good shop is: If they won't take the time to show you and help you understand, find a shop who will. Even if you don't understand what they are saying, their willingness to spend that time with you is the key.

There was another car I've worked around in the past that was prone to rear springs getting 'soft' and destroying the rear tires. I forget what car it was, but it caused a similar issue to your tire wear. I've yet to see a 911 over 5 years old without the rear end 'sagging' a bit. I'm sure one of our more engineer types can chime in, but that's my hunch when everything else 'checks out'. Even after an alignment, both my 01 and 02 turbos exhibited what I consider 'bump' steer on bumpy roads.


Does anyone know if the Durametric software allows us to calibrate the PSM when on an alignment machine?

 

I would think a "wobble" of any kind would be felt while driving and would not have been allowed to continue long enough to create this kind of damage...

 

My rears looked exactly like that if not worse I only realized it after I got a flat!! Car was smooth at speed no wobbles. I got 16k out of some pilot sports so I thought that was o.k. Do you think I could have scratched out more miles with an alignment adjustment?? Car is stock euro ride height.

 

Wow, that looks terrible. Does anyone think the spacers can attribute to that?

If you decide to try to change your wheels bearings yourself, do a DIY please, you were very helpful for the clutch accumilator and the slave!!!

 

I will with pleasure D_Nyholm. I am also really happy if the slave replacement was helpful.

I had a look at the tire wear before addition of spacers and the wear was already present... But I will ask that question to the alignment specialist next week.....

 

My car was also really smooth and about two weeks ago I was able to reach 290 km/hr (180 mph) without any vibration and straight like an arrow..... I will let you know after I meet this other alignment specialist sometimes next week.

 

Finally a good result. There is some day when everything seems to be perfect. Today at 08:00 I was in front of a place called "Garbis Alignment" in Laval north of Montreal for a second attempt. Instantly, I realized this guy knows about Porsches and he love his job. A bit more than an hour later I was driving my car back home and could not believe how perfect the car was....

Rear bearings were OK, no problem involved by the addition of spacers, one probability was low tire pressure, the overhaul adjustment was not too off but of course it is difficult to say since another shop tried to adjust it before....

Thanks every body for your feedbacks and helps!

 

glad to hear it...we like happy endings

 

glad to hear that everything is ok now
