  1. I had oil residue in that area above the spark plugs and on top of the right rear cylinder head.  That corrugated line, It. 4 in the diagram posted, apparently had some minute cracks in it and was seeping.  I replaced that line and solved the problem.  Admittedly, I replaced the AOS at the same time so can't say for sure it was just the oil line but it had to contribute for the oil to get to that location.

  2. I don't mean to start an argument with this, but just adding some info.  My '04 Cab has the optional factory side skirts and rear wing.  I have studied the 2004 Cab option list and apparently no front spoiler was available so this is as close as the original purchaser could come to buying an "aerokit" for this car.  Porsche must have considered this combination of parts OK w/o a front spoiler.

    I also question whether the aero imbalance issue is relevant at normal speeds and might only come into play at Autobahn speeds (as in 100 MPH plus)?

  3. OK, I am all done except for final torque on the axle nut.  The tools worked fine.  The job, as a whole, was a physically tough PIA for me.  Working the axle shafts out and back in, dealing with the hub removal from the bearing, etc.  This is working alone but with a lift.

     

    If this really is a 2 hr. per side labor charge at the Porsche dealer, I would recommend just paying them to do it.  I would love to watch this job done in 2 hrs. per side.

     

    BTW - would it be good practice to put some anti-seize on the axle threads or just leave it dry?  340 ft-lbs seems like it would like some lube.

  4. Well, right or wrong, I bought the CTA 8650 tool kit, which I think is a knockoff of the SIR kit.  It was under $300 delivered.  I have also purchased the bearings from Sunset to do both rear wheels.  It will be a while before I get to this project but, when I do, I'll provide some feedback on the tools and anything helpful to future DIYers that I learn.

     

    Thanks for the input from members.

  5. I have read the DIY and old posts until I am cross-eyed.  I think I have a handle on this but, just to be sure, would someone in the know just review my list please?

     

    I have a hydraulic press.  It seems I have the choice of removing the carrier/hub and R&R the bearing using my press OR if I purchase a bearing removal kit like the SIR tools I can do this work with the carrier still mounted to the car.  Is this correct?  I am actually leaning towards buying the tools just to minimize the amount of parts I have to remove.

     

    I have read there are bearings with a magnetic disc inside for the speed sensor and that this needs to be correctly oriented.  I have also read this applies to 2005 & newer cars so this is a non-issue with my 2004?  Confirm please.

     

    I have read the bearing sourcing discussions and I'm sure the F A G or NTN equivalents are fine, but for the money I plan to use the Porsche part.  Doesn't sound like a job one would want to do over and I'm hoping using the Porsche bearing will ensure this doesn't happen.

     

    Any other comments or suggestions before I dive in?

    I finally replaced it with the NSK cylindrical bearing.  After ~500kms, not problem so far.  The original bearing was dual roll and they are still in great shape after 160K kms.

    I also went with the roller bearing. RND retrofit in my case.  Time will tell if we made a good decision, but I think a car with a lot of miles on it and the original IMS bearing will likely do fine with pretty much any new bearing you use.  The LN "Solution" is clearly the superior approach.  It was not well advertised (or, in my case, understood) when I did my retrofit.

  7. My info is all 996 so the 997 could be different, but I think the part you are talking about is Item 19 in this diagram.  I have also attached the page with the p/n, which notes as being for a C4S (these have a center radiator, right?).  My '04 996 had evidence of having had this piece installed at one time but I don't know why, since it is a C2.  I hope this helps you get some info on this.

     

    If I were you, I would just buy this part and replace your damaged one.  As you have agreed, Porsche put it there for a reason.

  8. I hope you get a definitive answer on this.  My 2004 996 C2 has the slots under the front bumper cover.  I have found the rubber deflector in the parts catalog before (though i can't find it right now) but it is listed a being a C4 part.  I find this odd, because I think the C4 bumper cover is different than my C2, so why does my bumper have the slots?

     

    I have been told it is there on cars with a center radiator and that it enhances airflow through that 3rd radiator.  Don't know if that is true or not.
