Hi everyone,

The upper balljoints for both front wheels on my 1985 900i are shot
(broken boots, etc.) and the only part where I'm getting stuck is getting
the ball joint shafts out of each respective swivel member. The Bentley manual says not
to use a generic ball joint separator fork.

There is a Saab special tool (# 89 95 409) shown but is a substitute tool
available from anywhere else? Short of being able to get a Saab tool or a
suitable alternative, what other methods can be used to get the balljoints
out of the swivel member?

I've emailed the people at Samstag Sales who sell a
lot of specialised automotive tools to ask if they know of a good
substitute to the Saab tool. I'll forward whatever info I receive back
unless the people from Samstag reply directly to this posting.

Regards,

Craig.

i've used a standard ball joint splitter with no ill effects. IIRC, the manual states something about possible damage to the steering swivel member.

i just make sure to not bottom the tool out against the member, and whenever possible, pound it towards the center of the car, so as not to torque the control arms as you are pounding with the mallet.

oh, and if you make the mistake of using the closed end of a wrench when installing the lower ball joints... it is cheaper to cut the wrench off than to pound out and damage the ball joint. personal experience...

(im ready to get slammed concering the research and developement that goes into the design of such parts of the car and how such a warning would never be stated if there was not some sort of chance of doing some real damage if a tool is used improperly)

*shrug* i use the regular ball joint tool and it works fine for me. if you do damage your steering member, you did read the warning

Thanks for the warning.

In the meantime I've been hunting on the Samstag website and located <a href="http://www.samstagsales.com/stahlwille.htm#Suspension" target="_blank">
some balljoint tools</a> made by Stahlwille!

I've never purchased this sort of thing before so what are everyone's views on the quality/value of these tools?

Thanks,

Craig.

PS. As a side issue, I also found a K-jet fuel mixture adjustment tool on Samstag's Stahlwille tool page. That looks to be the exact tool needed for adjusting the fuel mixture on K-Jet equipped Saab's too, so it could be a useful thing for people doing regular work on K-jet fuel systems...

Craig,
Adjusting K jet - you want to move the plate or twiddle the mixture??
Mixture twiddle is easy, use a long 3mm allen key

Adjusting the plate hieght - careful use of the fingers to adjust the plate height works

Ball joint splitters et al

I have changed them before and have found it's easier and quicker to take the whole hub assembly off the car to change them.

<ul type="square">
[*]Block of wood under upper arm.
[*]Undo driveshaft nut
[*]jack car up, axle stands please!
[*]Disconnect steering track rod end.
[*]Undo caliper, hang to one side.
[*]Undo top and bottom ball joints/ suspension arms.
[*]remove to bench
[*]Undo Ball joint nuts!
[/list]

This way you have room to get spanners and sockets in without loosing them!


I have found that rather than using a splitter I have used a air chisel tool. I have modified a round "spike" (blunted the end) which delivers enough "shock" to pop the ball joints as well as the track rod ends without damage.

Cheers
Malc
