Suspension ball joint - NEED HELP
« on: November 25, 2021, 11:45:39 »
Dear All,

I need you help.
I have an MKIV (AK1317)

I have noticed an increase noise on the front left of the car especially when driving on poor quality road.
looking at it carefully, I have noticed that the suspension ball joint of the upper whisbone  left is dead (see picture) .  I want to change the 4 of them (2 left and 2 right). Does anyone know what is the part reference and where to fond them ?

Also I have noticed a sudden degradation of my right tyre (degradation on the outside of the tyre). again looking into it carefully, I noticed 2 things:
- some spare movement of the lower suspension ball joint (see picture)
- noisy wheel bearing when spinning the left wheel manually

Again, Could anyone help me with the bearing and ball joint references and where to find them.

Many Many Thanks in advance for you time and help
Best Regards

Hi Laurent,
I think the lower ball joint is a Saab one. As far as I know Barry (bazhow@hotmail.com) offers a NOS set of them. Look at the "small ads" page above the forum.

The upper suspension ball joints are standard male threaded rod ends. I am not sure about the thread but it is definitely UNF. You can buy them here: https://www.isa-racing.com/detail/index/sArticle/4086/sCategory/970 or here: https://www.mcgillmotorsport.com/male-rod-ends-c-55
I bought from both companies over the past years and both are very good.
Kind regards,
Peter

Laurent,
The upper rose joints also set the caster/camber so either mark up carefully /measure (count turns) or follow the guide I wrote up in action a few years  back.
I may have the article in "word" somewhere buried in my pc if you want a copy.

I used Mcgill motorsport.

Thanks Peter.

I think the upper Rose joint is a 5/8"  3/4 UNF thread.  I'd noticed McGillMotorsport was selling them but had no idea if they were good. Really nice you can confirm they are.
The lower rose joint, I thought it was an Austin 1800/2200 part - but I might be wrong. I'll ask Barry to send me pictures of his parts.

Many thanks again for your help .
Best Regards
Laurent
Many thanks

Laurent-re the wheel bearing --the one in place should have a code number on it to get a replacement.
I found the adjustment article so will email.

Other respondents are correct, the ball joint is a Saab part and should be easy enough to get. It is tricky to change though. If you have my experience, you will have to modify a spanner to get into the recess and stop the unit rotating, as you try to remove it.
 You will need a ball splitter. Mine is very heavy duty, but despite extreme force, the taper would not release. As a last resort I carefully used a blowtorch to force the unit to expand, while the splitter was in place. Shortly after, there was a loud noise as the two parts finally separated. After which the repair was straightforward.
