...not to mention you'd need a lathe, knurling tool and a hydraulic press ....

HOwever I am just going to buy new parts and replace...that way I can cross that off my list for quite a while.

Dang,
Thanks for all the replies and discussion.

Going with the 987 links sounds like a no brainer.

and you **WANT** the 987 pieces.. trust me. I gave you the correct part number. You will thank me the first time you drive the car.

TeamOx? You work for Pelican?

what is the difference between the 986 and 987 part??

sb01box · 08-17-2014, 07:50 AM

there's other posts that indicate that the swaybar drop link may also make rattling noise at low speeds.
I cheaped out and replaced all the drop links. did not solve the problem
replaced the lower control arms and no more noise. went with TRW parts. that was 30K miles ago My car is my daily drive so no heavy driving, and when it comes to suspension/drivetrain parts, I always go with original or oem parts - not a voting contest and an amateur weekend mechanic at best, but I'm aligned with Brad's comments.

Pdwight · 08-17-2014, 11:05 AM

The 987 is a TRW part, it is an OEM part...who do you think makes Porsche's

It on Renntech. Under Boxster control arm repair

Had this done on the Boxster.
Worked like a charm.

The clunk is gone.:dance:

Need to order some, sounds like I have a pickup box full of loose lumber on poor pavement and rough dirt road I had to do to pick my son up this afternoon.
I've found the 986 part at a reasonable price but not the 987.

EJ-Fresno · 05-30-2015, 05:46 PM

Now I know what that frigging noise is coming from, and how to fix it...

KRAM36 · 05-30-2015, 06:33 PM

I just ordered the 986 rear track arms for my car. Now I'm curious to why the 987 is better?

987

986

EJ-Fresno · 05-30-2015, 06:42 PM

I agree with you Kram. I am curious about the difference?
I came to the conclusion that they were both the same and ordered some 986 ones...

KRAM36 · 05-30-2015, 06:51 PM

I did not know they were interchangeable when I ordered mine. Normally when they are Porsche supersedes the part number. Maybe it's a build date issue, the 986 numbered track arms have been sitting around longer then the 987 ones? Once they run out of them they supersede the number?

Like if you go to Pelican to order a motor mount, you now get the 987-375-023-05 part number.

flaps10 · 05-30-2015, 06:58 PM

Not sure what the exact difference is, but beware that Pelican has a ton of "file photos" on their parts pages. I thought i had gotten the wrong clutch slave cylinder because of it.

On the subject of the track arm i watched the video from EPS about theirs with the urethane bushing. I like some EPS stuff but not that. If you watch him push the thing around you see the arm bending quite a bit. That track arm isn't designed to bend and with a ball in the end it never will. Look up "pin connected structures" in any statics book. Each member is statically determinant (just means a mortal can do the math on all pieces of the free body diagram) because they can only push or pull, exactly the job of a track arm. Counting on that flimsy forging to stiffen the ride is a suckers bet in the long run. I bet some of those will snap off a few inches from that end. That would be "interesting"

I have to agree with Brad Roberts on this one. I'm hoping he will explain the 987 arm better

There used to be some aftermarket replacements available with greasable spherical joints at very reasonanle prices here in the states. Wonder what happen to them?

Not as cheap as I remembered but I guess it a sign of me getting old...

Has anyone here used these? Care to do a review?

They look heavy.

Is the ball joint free of plastic? Do they have the potential to outlive a stock set.

I'm planning on lowering the car and was looking at their toe control arms. Is there a need for adjustment on the trailing arms?

healthservices · 06-01-2015, 01:18 PM

Well if it is all metal, It may not be as durable. Once a little play sets in I'm sure you will hear it.

You're probably right.

Just blown away that a cars trailing arms are shot at 60 000 miles and the hole part has to be replaced. Would rather press in new joints. Seems wasteful.

healthservices · 06-01-2015, 03:48 PM

That is what is possible with the part I showed. Whether or not the rod end is easily available is something else. May want to contact the manufacturer or the seller to find out.
