I'm pressing wheel bearings into the wheel carrier on a 997s. Can someone please advise if they go red (bearing seal) side out or black side out? Both sides have a radiused edge for pressing and I don't have a reference.

BTW- these are *** brand (no jokes please) not OEM.

Thanks!

no idea but i'd like to know also, in case i ever have to DIY. i say call the manuf and hope someone speaks english. otherwise send them an email?

how long did your old OEM bearings last?

look it up on renntech web site, for 996 cars, it may be there.

Haven't done these on a 997, but it looks like the black side is magnetic, in which case that would go in for the ABS sensor, and the red side would go out.

I've heard this and you can actually see the socket for the ABS sensor in the pic. How do i tell which side is magnetic- it is literally magnetic or is the inner race just a different ferrous (magnet friendly) shape.

thanks

The dark grey portion is the polarized portion. It's not actually magnetized, but it is made so that the sensor can pick it up. I do recall the workshop manual stating not to touch it with a magnet.

the dark grey seal right? thanks

I asked around and the grey part is indeed polarized. Phew. If you install it the wrong way you get an ABS failure.

Thumbs down on this one to the folks at DC auto. I called before starting this thread and they said I could press it in either way. I bought the bearings there. Totally bad info.

Good to hear you got that resolved while avoiding a catastrophe. *** brand, made in Slovokia....that's just an open door, and I'm impressed that we made it this far without some colorful dialogue.

OK Xr4Tim, I'm feeling stupid...how did you determine that the "black side appears magnetic"? Of course I'm looking closely for metal filings sticking to it, etc. Is there something in the letter coding that means "magnetic"? And for all these years I thought *** alluded to cigarettes....

The red side feels rubbery and the black side feels like a refrigerator magnet. But it's not magnetic, it just has ferrous material behind it.

There's a tool you can use to double check:

I've done Cayenne wheel bearings before, and they look the same. I knew from reading the workshop manual which part was polarized.

Bump for this thread. Just installing a wheel bearing on a Cayman and had the same question.

Have a serious press on hand. The spindle does not go in easy.

The bearing itself went in very easy into the hub. I just put the bearing in the freezer overnight and left the hubs in the oven at about 275 F for 2 hours. I had to use my welding gloves to handle everything but the bearings fell right in.

I did bearings into hub and then spindle into bearing. It might be worth trying the spindle into bearing first then bearing into hub.

I can't remember exactly how i fixtured everything to get the spindle in place but it was not easy. Have a helper on hand.

Good luck!

Thanks. I have the SIR bearing press kit and everything went right back together, no helper required. Didn't heat up the carrier quite that hot, but the bearing went in easily. Then after the bearing warmed up I pressed the hub into it, no problems. The biggest difficulty was getting the race off of the hub. Only took about an hour to put things back together.
