Folks,

I started noticing this intermittent creak/groan on the driver's side front suspension, every time I egress the car, after a spirited drive. 

I have had some creaking due to the lubrication loss in the ball joint area from the rear and have used the hole-in-the-rubber-boot to inject grease to keep the noise from recurring. I did the same for the front, just to be sure.

This noise puzzles me.

Based on my research, it may be the front strut mount bearing but didn't want to go about replacing parts without your opinions.

It doesn't occur when the steering wheel is moved from corner to corner though or feel different during a drive.

Shows up only when there is downward pressure on the foot area in the driver side, during egress or when pressure is applied on the car side fender over/near the strut area. 

Here is a video of the latter, for audio on two creak/groans between the spring movement.

Appreciate your insights on what this can be...

My car is clocking nearly 173K ...so wondering if this can be a simple DIY  or figure out the need to have a complete strut bearing and/or strut replacement.

 

Thank you,

V

Ah ha...Thanks again, JFP!

Any way this can be lubbed like the control arm ball joint boot, or does it need a straight replacement? I see that that access is via the 3 screws under the frunk...but don't get a clear line of sight to the bearing area.

If the bearing is weak, can the strut not be far away from needing a replacement?

I did the bounce test on the strut and it returns back without any oscillation, when pressed down.

It is not that simple.  The strut bearing swap requires removal of the strut assembly, compression of the spring, and then disassembly of the strut itself to get at the bearing.  And after putting the car back together, you will need an alignment.   If the strut cartridges themselves have a lot of miles on them, or show signs of leakage, etc.; now would be a good time to replace them as well.

3 minutes ago, Loren said:

Strut work should always be done in axle pairs. That is... do both sides.

 

Good point!

Sounds good, JFP and Loren.

Ball park - what should I expect to pay if I had to have this work done at an Indy shop?

Strut mounts, struts for both axles, alignment and labor (@ $100/hr).

I'm spending a bit of money on the car lately - miles and age being big factors, so trying to establish a baseline to what is in store for me w.r.t. maintenance cost, moving forward vs. smiles out of the car :)

I would budget for between $1000 and $1300, depending upon what parts need to be replaced, all in including alignment for the front struts.

Quick follow-up, my Boxster has the M030 suspension in it now.

Does it make sense to upgrade the struts, and would the Bilstein B6 be a good idea?

Mine is mostly a street car with lots of highway driving.and with rides around twisties whenever I can.

Would I notice a difference in the ride quality with the B6s? Does these struts tend to lower the car too? or should I stay with the stock ones in the replacement?

Hi,

It took a few tries - I was able to get rid of that groan/creak by lubbing thru this area on the strut tower,

 

" I see that access is via the 3 screws under the frunk...but don't get a clear line of sight to the bearing area."

This lubricant has worked well for me.

This was about 9K miles ago and no sign of that noise since then. 

Hope this helps.

 

Merry Christmas!

 

Thanks,

Vish

      Hi Guys, 
       
      So for my car , 996 C2 , 2003 with 70 TMiles and M030 suspension .
       
      Im currently in process of purchasing several parts for suspension refresh , so to say . 
      Whole process came to a corner , left or right  , from perspective of refreshing it since rear shock absorbers , i have planned to purchase are not available , anywhere .
      At least not for reasonable/decent  price 
       
      Plan is  to refresh my stock M030 shocks , front and rear , where Bilstein B4 is standard which came with car .
       
       
      Now , i have received front shocks but rear ones are not available and supplier does not know when they will be available .
      I could not find them online , also , not a single supplier have them on stock, so only option , order them , pay them and wait for Bilstein to make them and deliver .. 
       
      Development of situation is is that my supplier have offered me Bilstein B8 as option , more or less same price as B4 .
       
      Now, guys ,.. 
       
      As part of refreshment i have bought several additional parts, which are part of suspension and fit B4 setup, for all 4 corners.. 
       
      supporting mount
      hexagon nut M 10
      compensating plate 
      ring
      bellows
      additional spring - bump stop
       
      So to say rubbers and plastics ..
       
      Springs i plan to keep , so no new springs planned ..
       
      Questions
       
      Will all those part be usable with B8 shocks , so plug and play .
      What will be height difference , is B8 height adjustable or height is same as M030 
      WIll B8 shocks be delivered with installation manual 
       
       
      I have read recent article , it seams, came in right moment for me 🙂
       
       
       
      So positive opinion on Bilstein B8 , which is ok , but im not worried about  B8 on German Autobahn , my worry is as i wrote , will this be plug and play considering replacement of current ROW M030 
      or something needs to be bought specifically beside refreshment parts i have already bought .
       
      Have some experience with wrenching around , front shock mount , Wheel bearing , basic service  , sparks, mufflers , ignition Switch , etc .. 
      But few additional thingies and advises  as additional knowledge is always welcomed .
       
       
      Thank you very much guys ..
       
      Zoran

      My front wheel was making a rattling noise for about the last week, and this morning as I drove out of my driveway and turned the wheel, I could hear a loud popping noise coming from my wheel whenever I turned. My best guess is that I drove over a pothole and the control arm / bushing moved out of place. Would this be covered under the OE warranty? Or should I take it to a mechanic?

      Pulling the front end on the GT3 to get at a dead horn... found the dust boot on the front strut torn.  Has anyone replaced one of these?  I had a competition suspension set up from Jae Lee at Mirage in San Diego and don't want to mess it up, but need to replace the boot.  Can I just remove the mounting at the top and drop the suspension and replace the boot from the top?  ANy help on this is greatly appreciated!

      I recently did a suspension overhaul when I replaced my inner CV joints out of necessity.  Problem I am having is they cannot align it properly. Because of the lowered suspension and change in geometry the rear toe in is more than it should be. I have ordered a pair of rear control arms from TRS to allow for adjusting toe, hopefully. So now I am looking to replace the Meghan racing tie rods with something that will allow for greater adjustment for proper alignment of the front end. Does anyone have an experience/insight into this type of setup for the street? Can anyone recommend outer tie rods? Will stock factory ones work?
       
       
       
      List of what was replaced:
      All wheel bearings with *** units repacked with Hi Temp synthetic grease
      All 4 struts/shocks with Bilstein B8's along with upper bearings/caps, bump stops, dust boots
      All 4 springs with H&R 29779 Lowering springs (Blue)
      All 4 lower coffin bars/ball joints with Meyle units
      2 rear track arms with units from Vertex auto.
      2 rear control arm/ball joint Meyle units.
      2 front track arms not sure if Meyle or vertex auto.
      2 Inner tie rods
      2 outer tie rods with Meghan racing units, adjustable blue color
      4 Drop links with Tarrett adjustable units
      Eibach 26mm front swaybar along with bushings
      factory 19.6 rear swaybar along with bushings

      Has anyone installed 08-10 Cayenne Turbo S lower control arm in 955 S.  I have MY04 Cayenne S.
      And can MY06 955 CTTS LCA be installed in MY04 CS?
       
      part number for MY09 CTTS is 955-341-017-61.
      part number for MY06 CTTS is 955-341-017-50
       
      I went to the dealer and compared the two, they look almost identical except for a little bit bigger outer diameter where it joins the upper control arm.  It is the #3 bolt location that seems very slightly larger in outer diameter.
