What is the best replacement control arm out there?
I have some clunking going on behind me in my 2002 986 non s. I am being told that I need to replace control arm part number 986.331.043.07 at a cost of $220 per arm. I have seen various threads talking about TRW, Deutsche Parts, Porsche OEM and the rebuilt Vertex arms.
I would like to hear from folks that have installed and run these for a while. What are your experiences and preferences of the above brands? I am leaning towards the Vertex with the stiffer bushing but I'd like to hear some opinions before I spend the $$ |

I am installing TRW arms on my Box today to replace the URO arms I installed 2 years ago. 1 of the URO central bushings has moved 1/2" upward from the control arm. I am sure it would have continued to move further out but the track arm contacted the control arm & was rubbing it so I have to replace the track arm also. TRW makes these parts for Porsche. I considered the rebuilt Vertex arms but like Deutsche their reputations are not the best & having to do this work twice is no fun. :mad:

They look like they may outlast the OEM which is the only way a non track guy could get the value out of them.

Here's the guide I used: "Posted June 06, 2008 - 12:44 PM The replacement of the 986 rear control arm has been covered in previous treads. This post describes the possible REPAIR of the rear control arm. You might as well try it since you can allways by a new part if this fix does not work. First remove the control arm. Clean the control arm and remove the rubber gators covering the main bushing ( 2 ). Then support the bottom of the bushing housing with a large socket to where the only contact is on the bottom crimp. Then use a 1/8" flat punch and lightly dent the roll crimp around the entire circumfence to tighten the original crimp to take out the axial plat that causes the noise. Note that only ONE side needs this treatment. Lubricate the ball joint and reattach the protective rubber gators. Reinstall the control arm and test drive your quiet Boxster. I did this repair on my 2003 Boxster S last year, 3000 miles ago and it is still performing as new. Saved $ 600.00 in parts. , Acomplish this repair at your own risk!" http://986forum.com/forums/uploads01...1355652192.jpg |
I had a similar noise, replaced the track arms with the ones from Vertex. They were a pain to install due to the urethane being so stiff and making that conform to the suspension geometry. I ended up having to load the rear suspension to get things lined up for reassembly.
Another important point: the Vertex rebuilt arms are too large at the body mounting point. The diameter of the washer/grommet that captures the urethane is to large and does not fit in the allocated space on my 2000 986 S. I had to grind a section of the washer away to make it slide into the opening and get the bolt through, this is kind of a bummer as it seems like a major oversight from Vertex. Just an FYI for anyone planning the Vertex track arm replacement... Most importantly, the rattling/clunking noises from the rear suspension are gone, now other squeaks and rattles are more noticeable. :-P |
