Trying to find a click noise after installing Bilstein HD Struts - all around into existing M030 Springs.
Wondering if anyone has the work shop Manual - Schematics - to share?
Solutions and common issue thoughts and suggestions are welcomed !!

Led to think after reading a few posts that the Bearing may be gone in Drivers Left Shock Mount.
Part # 993 343 018 00
I looked at the PET drawings, part # 9 - No Bearing visible.
Apparently there is a Bearing inside?

Car is a 97 C2 133 Miles
M030 - Sport Suspension

Suspension Bushings have been inspected by Mechanic and advised all are good. No Bushings have been changed to date, based on review of Service Records - NONE.

Recomendatiuon is Remove front left drivers strut for Inspection.
Figure I may be able to attempt this.
Issue occurs while pulling from a parking lot, higher surface onto roadway / driving away over curb onto the road while turning left.

Any thoughts?

Second, if these are the culprit would upgrading to an adjustable Rennlne be the way to go? Trying to get ready for DE events this year so want the kinks out. This is before entering Slippery Slope, Car is all original. Stock.
Thanks Tom

 

Attached is the PET Drawings

 

I dont remember there being a bearing in the stock mount (been awhile since I looked at a stock one though)...

First thing that comes to mind, is to make sure the spring is seated/clocked correctly in its perch. Assuming that is good, pull the sping and articulate it by hand...

That being said, can you remove the tire, put the car on stands, then lift/lower the control arm with a jack?

 

yES I can start there. I did take the car into the mechanic. I ***/u/me he considered this - reply was Suspension all good. Bushings Good. Noise is still there so he said lets examine Struts.

I have seen a few posts with clicking or thumping after installing Bilstein HD struts with M030 springs - I do not know how the issue was addressed - solved other than possibly changing strut mount.

Looking for suggestions toward a solution - based on others experience.
Jackals stated damage was unlikely to the strut mount unless above 100,000 miles - here I am.
I will give your idea a try.

I do not see any bearing in the PET drawings but I see on the Rennline site:
Front Adjustable Camber Plate Top Mount Set- Sealed for Porsche 993/964 - Rennline creation? with a spherical bearing - but perhaps thats for Camber adjustment / lock?

Thanks for your reply
Tom
Thanks Tom

 

FORGOT TO MENTION: DRIVER SIDE FRONT TIRE IS FEATHERED ON INSIDE

 

I FORGOT TO MENTION:

DRIVERS SIDE FRONT TIRE IS FEATHERED ON INSIDE

 

Yes, there's a bearing in the shock mount, assuming you mean PET part #2, rather than 9 as you indicated. If it's like mine was, a cleanout of old, dry grease and a repack wouldn't hurt. Although it bears a fair bit of pressure, I doubt it would wear excessively with the relatively small amount of rotation it would see in normal steering, even dodging slow traffic on the 401.

Feathering on inside left could be bad alignment, or wear in suspension parts.

Have you checked steering (tie rods) and front control arms (a-arms) for play in ball joints? Also, is the drop link well secured to anti roll bar?

BTW was that pic taken on the Cabot Trail?

 

Could the spring be squirming around on its seat?

 

YES - HECK OF AN EYE!! That indeed is the Cabot Trail. 8/2013

Like the 401 quote - Most borring hway I have ever seen - Too Many Times!
Only fun once was Ganonoque till Planes became a Concern LOL

Bak to the car - seems Suspension according to Nu Wrench is All Good.

But I recall when I purchased the car and had Rear HD Bilstein Struts installed the Rear bushings showed some wear but was still acceptable.

The roads on the trail, in sections , made me very uncomfortable at speed. I did not like the road feel so I think it is time to consider all Bushings - Again.


Sounds like I will have to Remove the strut and Inspect #2 being Part #
993-343-018-00 Mount - Right?

This Does Not show the Bearing ? I looked at Jackals-Forge post on Suspensions and he showed a Bearing in the Mount.

Now if this is the cause, and its a Good Idea to inspect/ Test and Clean!! Thanks.
Would it be wise to move to a Rennline Front Strut Mount with Adjustable Camber plate >? Or am I into something unnecessary?

 

Is your mechanic thoroughly familiar with the 993? Just wondering what his point of comparison is re: "All is Good", after all your car has enough miles that the bushings (esp,front control arms) will be getting pretty tired by now.

The Cabot trail should be a dream in the 993, if yours didn't feel planted through the curves (except maybe on uneven / broken pavement), something isn't right with the suspension. Might not hurt to get a 2nd opinion from someone who specializes in the 993 in the GTA, you could search here, or post for a recommendation from other local rennlisters.

Again, the shock mounts wouldn't be the first thing I suspected, but couldn't hurt to clean & re-pack as maintenance. Yes, the part # and location is as you noted. Bearing is internal to the mount, you can see the seals reddish-orange in the pic below, photo credit to jackals-forge:

 

Hi Brian

Yes, I am advised Mechanic is well qualified - worked on a few race teams - wrenched as well as Trained at a few Large Shops b4 opening his own shop - which has a Good Rep!!

On the other hand, I wondered if I missed the garden as I was walked down the path.

I think it is time to look at all the Sprinds, then Mount and Bushings and go from there.

We were just hit with another snow storm - likely freezing rain - but hoping to get car into a friends shop so I can complete the front end analysis / investigation this weekend - or real soon.

 

Hey Brian

Not sure if u recall chatting with me about the Strut Mount???

Wondering if u have some time to share a few thoughts?

Now that spring has returned, I noticed you contributed on a few threads I have read and would appreciate your insights.

The strut mount - clicking and thumping of M030 Bilstein HD / Strut Mount issue.


Turns out I think the Mechanic was taking me for a ride
Justifying his own existance - leading me down the Garden Path.

I think I have found a More reasonable GTA Mechanic, buit I found out a few things - or have learned a few Nu things

To remove strut mount - Need Spring Compressor
I do not have this

How do u Clean the Strut Mount Bearings??
U spoke of re-lubing to see if issue goes away.

I found a crack in the rubber on the Front Left Stabiliser Mounting.aka Drop Link?
Crawling around, taking pics on different angles, on the Ground, I see the damage. Will try to attach a Pic.

Wondering if this is a SYMPTOM ? of the strut mount Bearing Problem?
Any Thoughts or Recomendations

Oddly enough, I did my DE Intro at the New Mosport - Canadian Tire Motorsports Park - Driver Development Track - 2 weeks ago.
Had a Blast!
BTW The car worked well.
Smooth Pavement
No issue with the strut - No Clunking or Thumping - sounds like a strut compressing or working I guess? Perhaps due to Smooth Nu Pavement

Then after DE I figured ok, this noise on the street is getting worse. I ne4ed to deal with this for my First DE - next weekend - now I think there are Two Issues.

Thats when I put the car up in the Air and found the broken rubber on the Stabiliser Mounting - aka Drop Link?

Now to refresh your Memory, back in October the Mechanic told me my Suspension is fine!!

I suspect the Damaged Drop Link is New 0r is a result of the DE ?

I need to get to the Bottom of this.

Do I have to change Both Strut Mounts at the same time???

Thoughts

Recomendations???

2nd Can I use white lithium grease on the O Roing for the SAI Fix?

Hey Tom, glad to hear you're having fun with the car. We had 20cms of snow in Calgary this weekend.

You can buy a spring compressor for $20 on sale right now at Princess Auto:

Cracks on the drop link rubber are caused by age and nothing to be unduly concerned about. They are not related to your strut mounts. If they split or are cut by foreign object damage like small rocks on the road, you need to deal with it as dirt can get in and cause damage and eventual failure. In this case, you could replace with stock drop links, or Taretts as I did. Or you might be able to replace just the rubber, provided you clean and re-pack the joint with grease; see here for replacement rubber boots for many applications: http://www.sealsit.com

I didn't take any good pictures of when I cleaned the strut mounts, but once you get them off it will be easy to figure out. If memory serves, there was a bearing cap that popped off easily with a small screwdriver or pick; the bearings were captive in a cage and the grease in the bearings and races was pretty much dried out and useless. I cleaned everything up with varsol then brake cleaner, and dried throughly, then re-packed them and carefully fitted the cap back in place. After you clean them, and before re-packing, you could do a trial re-assembly to check for excessive play that would indicate the bearings are badly worn.

If replacement is necessary, I would do them as a pair. Stuff like that always seems to wear at about the same rate and you don't want to pull everything apart again in a year to fix the other one.

Re: o-ring, sai fix- is this the thread that you mean, with writeup by Paul902?
https://rennlist.com/forums/993-foru...-manifold.html

If so, that thread is about a fix for an oil leak under the varioram, not for the SAI. In any event, I wouldn't use lithium grease on an o-ring, best to use dow corning molykote 111. I couldn't find it at my local auto parts place but if you are near a scuba shop they will sell the same stuff as o-ring sealant for dive tank o-rings, a bit pricey but you don't need much.

Note: If you're like me, it will take while to DIY any of this stuff so if you've found a mechanic in whom you have confidence, you might want to have them do the work to get it done quicker. You don't want your car out of commission for too long while the all too brief driving season is upon us...

Have fun and drive safe!
Cheers/bc

 

Just re-read your post, did you say there was broken rubber on the stabilizer bar mounting, that is, on the metal bracket that clamps the sway bar to the body? If so, that's probably what's causing the bump/clunk sounds. Post a pic here if you're able, thx/bc
