A second hand strut I bought is missing the ABS ring - The Unofficial BMW M5 Messageboard (m5board.com)

I just bought a used strut for my M5, but doesn't have the ABS sensors in the hub like the one I removed from the car. Everything else is fine, and have already installed it on the car (make sure it fit, and wasn't bent). I'm considering having it machined for the ABS. Anyone have any thoughts on what to do?

Buy an M5 strut, and not the early non-M5, non ABS strut you're using now.

Sounds like you have the wrong part.

Get the BMW part number stamped on the side of the strut you have just fitted and type that into the search part facility on Realoem.com

Example:

Strut is marked 31319065447 or maybe in format 31.31.9.065.447

You would enter 31319065447 into the search by part number here: http://www.realoem.com/bmw/partxref.do

Which in the example above would return:

"Part 31319065447 (FRONT LEFT SPRING STRUT WITH WHEEL HUB) was found on the following vehicles:
E34 M5 3.6 SEDAN, U.S.
E34 M5 3.6 SEDAN, Euro"

Hope this helps.

Regards

Ivan

I need to check out the part # on the strut. The thing is perfect in every other way though. From what I've been told if it wasn't the M5 strut it should'nt even fit because of the ride height is so low. It measure perfect to the original as well. Is there a way for me to use the hub of the old strut? I know this is probably a no!

Strut doesn't determine the height. Even if it was different , it will always fit. The chassis for the M5 is no different from other E34 in that aspect.

Wasn't it made from the 535i chasis only? How doesn't a strut determine hieght? It's like a leg of a table, but only with camber and caster in play with a spindle that isn't bent (the reason I needed a new strut). Please for my understanding, tell me how a srut does not determine the hieght. I'm talking measuring from the center of the wheel to the arch of the bottom wheel rim, and comparing both sides.

I would suggest that there are maintenance & technical factors discussed on a couple of your
threads that would be best addresed by looking at your own
vehicle closely.
Then a search of the internet & this Board will give you what you need to know.

The strut is approximately , what, 40-50cm high?

The distance from the top mount to the lower arm is at least 60-70 cm.

So, the spring that is settled on top of the strut determines the total length of the unit. Ofcourse, if there would be two different lenght struts, it would add up higher, but this is not the case.

Sorry if some of my questions are a little too amature. Just new and trying to learn, and cant seem to find a lot of info or data about the car other than history of production. Perhaps I will dig around through more old threads. Thanks!

No problem at all mate

Its better to ask than to do something wrong!
