Finally,
the boss handed out the 05 bonus checks and I think mine will cover the long awaited Koni Gas strut/shock install, corner balance, ride height adjustment and Hunter 4 wheel alignment. (plus some other goodies)
My car is an early 86S with 20 year old leaking Boge OEM shocks. I purchased a set of Koni Red's from ebay that came off a 85 928.
My question is can I use all the stock mounting hardware and stock spring perches for the install?
The Konis did not come with any hardware.

Thanks RDS

You'll use all of your old strut hardware and perches with the Konis. Keep track of how it comes apart and reassembly is the reverse.

Garth S

Yes!
Careful with the rear threaded adjusters - they can be tricky to remove.

Don't forget the JB Weld for the perch adjusters.. If not, you will be adjusting the perches to infinitely to nowhere...

RDS928S

Ok Gents,

good news. Thanks.
There is no way I am taking on that job. Our local PCA suspension alignment shop "Eurotire" in Fairfield NJ is handling the chore. They have performed many 928 suspension upgrades all with rave reviews.
Friday is the big day. Already have 928 Motorsports motor mounts and poly- graphite sway bar bushings installed. This should be the icing on the cake!


Thanks Again

The JB weld has to cure for 24 hrs. that means that if you reuse the perch adjusters, the car will be on the lift for 24 HRS.

Ask me how I know.....! And no one told me this, so i could have bought a set of adjusters and swapped the thing in a day..

That TICKED me off...!

TAREK

Not sure what that means. If you remove the assembly out of the car and relieve the tension off the spring by CAREFULLY (aim away, like you would a rifle) removing the top nut, no need to turn the perch adjusters

Garth S

Richard, I know I'm about to learn something new , so you JB weld what to what - and why?
Suspecting that you mean the threaded inserts so they don't spin needlessly when adjusting ... ?? If that's the case, on the other end of the stick, I installed the adjusters with a douple dollop of antiseize : A front one did spin initially; however, I jacked under the lower control arm to barely lift the car off its jackstand. This extra loading bound the insert to the shock step ring, allowing the adjustment to be made.
If not this area, I'm still guessing - but will save up for a tube of JB weld!

blau928

Garth,

The JB Weld is used to weld the threaded inserts to the shock body. Yes, it is to prevent the inserts from spinning so the adjuster nut can actually move up and down when you turn it.

If you do not weld it to the shock, you will not be able to adjust the ride height. And, as we all know, the suspension needs to settle before you adjust the ride height properly.. Once you lift the car up, you are back to a non reachable base line.....

I had to leave my car on a rack for 24 hrs for the JB Weld to cure, as I did not get an extra set of adjusters when I bought the setup......! That's why I was ticked off.


HTH,

MarkRobinson

you can assemble/install wet, just don't try adjusting the ride height until 24hrs or so.

ErnestSw

You can also do it without the JB Weld as long as you assemble them properly.

blau928

This is one assembley I would have to see....!

In addition how will you keepyour ride height adjustable...? The adjuster goes on a different spot on the Koni shock body, compared to the OE stuff.....

Even when assembled in the spring compressor and spring compressed, the adjusters and threaded sleeve turned together... Yes, this was with anti sieze on the threads, the base of the springs and spring perches....!

ErnestSw

One end of the threaded sleeve is tapered so that it jams over the stop ring on the shock. If you don't use anti seize and get the sleeve on correctly the adjusters work fine.

AO

Maybe so, but I have a one (front left) where the sleeve just spins! Still haven't fixed it, but I will soon - and I'll probably JB weld it. Thanks for the tip!

blau928

Why would you not use anti sieze on the threads and the base of the spring where all of the adjustment friction is occurring...? How does the aviodance of anti sieze on these parts aid the turning of the adjuster perch..?

This makes no sense whatsoever..

The set I assembled spun freely and needed to be welded. In fat, the instructions supplied with the parts required the JB Welding of the adjuster threaded sleeve to the shock body. It spun in the spring compressor when assembled.

My take on this is that a pair of threaded adjusters should be supplied with the Koni's, as they need this before being installed on the car..

Andrew's would not be the 2nd 928 that the adjusters spun on when not installed with a bonding agent....
