    I am getting a little confused. In English you have a wheel hub, where the wheel bolts onto. In the Haynes Swedish manual they refer to Hjulnav and in the CD parts catalog for the 96 (from the Saabklubben) it also refers to a Hjulnav.

    When I went out looking for a hjulnav they looked at me as if I was from Mars. In the end I managed to find out that its refered to as hjullagersatser.

    The reason I am looking for one is one of the front wheel bolts on the 900 broke off. I drilled a hole in the broken part and used a tap to remove it but this broke as well.

    I thought that it might be easier to get a wheel hub from a scrap yard and just replace it. So far I have not found one other than at Thomassons Pick and Pay, very interesting concept, take off what you want and pay very little for it. I found the right year 900 and couldn’t get the axle nut off. The cars are on block so that it is easy to get at all the parts, the only problem is you cannot stop the axle from turning so that you can undo the axle nut.

    Once I had the correct name for the part I was able to search for the hjullagersats. The only problem is, I can’t find out from the internet sites if this actually contains the hub or just the bearing set.

    Has anyone had experience with the fram hjullagersats from Biltema for a 88-93 900. Does this contain the hub or just the bearings.

    Any help would be appreciated as this is driving me nuts.

    Thanks in advance – Gary

    I belive the hjullagersats only contains the bearings and the price is about 500:- kronor.

    If the scrapped car still has working brakes you can put Elisabeth or someone else in the drivers seat and ask her/him to hit the brakes. This will probably stop the turning of the axle. You must press the pedal hard – the power brakes does not work when engine is not running.

    Kaparn – Thanks for the info. Saves me a trip, but will have a look on Monday on my way to the scrap yard. Hopefully I can build a bracket that secures onto two wheel nuts and touches the ground, should stop the whole hub assembly rotating so I can try get the axle nut off.

    Regards – Gary

    Bengt – Unfortunately the calipers have been removed by someone else, will remember it for the future, maybe they have another one in the next time I am there.

    If the brake disc is still there you can use a clamp to fix the disc. I think you can use the bracket for the caliper as a ”stop”.

    Bengt – The disc brake is still there but no caliper or brackets. But your idea of using a clamp could be the answer. Much easier than cutting and drilling a bracket. Will go outside and have a look at things and see what I can come up with.

    Kaparn – I have been trying to find a pipe that will fit over my socket but no luck yet. Will be trying other scrap yards to see if they have pieces. Still trying to find all the places to pick up the bits and pieces.

    One other question, will the front wheel hub be the same on both sides.

    Thanks – Gary

    Finally! All four wheel bolts are on the front left wheel again. A lot more work and running around than I first expected. Two additional trips to the scrap yard and I finally got a wheel hub, plus wheel knuckle housing, and the drive axle off the car. Could not get the axle nut off but once it was on the work bench, and a 1m long pipe over the socket handle (Kaparn – What a difference).

    My plan was to replace the complete steering knuckle housing. All the information I had gathered said that parts from 1988-1993 would fit, excepting I never took into consideration the ABS that is fitted to our car, and of course the steering knuck housing I struggled to get off the scrapped car didn’t have ABS, you live and learn. This is the first car with ABS that I have been working on so I am a little new to where the sensors are and what they are like.

    I managed to get a local mechanic to help me tonight to drill out the old wheel bolt and re-tap the thread, took 1.5 hours of his time but now the car is back safely on the road again. It sure helps getting to know the right people with the knowledge and proper equipment, will definitely be calling on him in the future, and his pricing can only be argued upwards.

    Tomorrow I will change the wheels, fit new hub caps and take a photo or two.

    Next jobs on the list, fit the tow bar and get a set of 4 mud flaps. It sure is fun when things work.

    It took a little longer to get the photo, but here is a link to a photo of the car as it is today, still a bit more to do, but it does look respectable.

    Thanks to all for the help so far.
