    Darn, I just had my car out yesterday for it's once a week maintenance/mental health ride and on the way back home I noticed a bit of uneasiness at speed. Then I entered my driveway and "CLUNK"! Once parked, I grabbed the front right wheel and pulled hard and...yup, something is not right. Sounded like loose lug nuts but they were all tight. I am hoping it is an easy to replace part, or something loose that I can snug back into spec but it wont be until the weekend that I can get that tire off and poke around.

    The funny thing was the quickness of the onset of the condition. I drive my car once a week and then to just suddenly find myself at an obvious out of whack place seems odd. I would have thought that it would come on more slowly. Fingers crossed!

    Broken sway bar support brackets are common too and fit the description perfectly.

    Thanks for the mention. I hope to get the car jacked up and pull the wheel soon. Pretty sure the problem will be easy to find. Hopefully easy to fix too!

    I JUST got the garage cleaned up and tools put away from a big tear down of my Ducati! Literally just got it finished up over the weekend, been at it since October and then the Ferrari goes....clunk! lol

    Shhhh...I think "somebody" got jealous!

    OK I have not had the need to jack up my F-Car so I discovered that my tried and true floor jack was not going to fit! That's OK I have been wanting to get one of those fancyt aluminum jobs for a while so now I have one! Looks my upper ball joint gave up the ghost. I feel comfortable performing this operation myself but I want to read up on a few threads first to see if there are any tricks or pitfalls to avoid. Which of you have done this?

    I read through Voicey's DIY thread for this and feel up to the task. Well providing I can find my arbor press! lol I know I have one but am not sure what box it is in!

    My only concern is if there is any chance of messing up the alignment by swapping the ball joint? I have not yet seen mention of alignment being an issue in the threads I found. In my mind the only chance to alter it would be if the bearing gets pressed into the hole a different depth than where it is now. Is that a legitimate concern? Or does the design of the parts dictate the position making it a no brainer?

    To keep it informative here is what I found so far.
    The clunk was heard when I grabbed the brake rotor near the top and pushed and pulled it. At first I thought it was coming from the bolt 1 and 2 area but after using a stethoscope it was clearly coming from bolt 5. This is the bolt that goes through the ball joint.

    Other things to note are that my bolts 1 and 2 were not torqued up as tight as 3 and 4. AND bolt 5 had loosened a bit so that the torque stripe was not aligned any more. It was about 5 degrees off. I am thinking that some extra vibration from the worsening condition was the culprit.

    I love the looks of those lightweight aluminium jacks, good idea for my birthday present list to give to my wife ... :D.

    Cheers, Bernhard

    I have that same Jack!

    Changing the balljoint shouldn't affect the alignment. It really wasn't bad at all! I'll bet the ball joint came unglued. And there are two circlips in the A-arm... and the balljoint is moving up and down in the A-Arm. Make sure you check the dimensions of the hole in the A-arm for the balljoint. IIRC I bought a set from AW Italian.

    It is the upper one he needs, so please do not send him the lower ones, Daniel ;).

    Generally, this kind of components might be considered to replace pairwise. At least I stick to that in most instances, except on very (!) lazy days :D.

    If the car was going to be up there for any length of time I would have popped a jack under there.

    I am ready to place an order with you once I figure out if my nice ratcheting arbor press that used to have made the move here or not! I don't want to buy any installation tools if I don't need them.

    You'll need snap ring pliers and an oven to properly cure the adhesive.

    Pliers...check

    I am up on heat application to ease installation and was going to use a heat gun but had not seen that heat is required for the curing. I can also freeze the bearings unless that causes an adhesion issue.

    I recall some 2 part epoxy "wetted" details pressed into the landing gear of fighter aircraft but never did we put the airplane in an oven for a cure cycle.

    Do you recall the name of the material that you are familiar with?

    This is the stuff that the factory specs: 184241 HYSOL EA 9360 (CONF.50ML) - Ricambi America, Inc.

    If the adhesive has failed you probably won't have much trouble removing the old ones. There isn't much of a press fit on these. The glue and snap rings are expected to keep it together. If the fit has loosened up (there is a spec for this in the workshop manual) you should replace the control arm.

    A poor design in my opinion.

    Don't be surprised if you don't find any trace of grease behind the boots. The last photo is from a 430 Scud. The boots were clean and dry.

    The glue does go off at room temperature in a couple of hours - if I'm doing this job out on the road then I'll use a heat gun to warm up the glue to get the chemical reaction going. I also keep the left over glue on a bit of card with a cocktail stick in it - that way I can know for sure when it has gone off.

    And one other thing... Hysol has a "use by" date.

    Stored properly (we have a special fridge for it here at Ricambi America), it is valid for only 1 year after the date of manufacture (DOM, on the label)

    Can you use part of the Hysol and then keep in freezer to use the rest at a later time?

    It needs to be stored in the fridge, yes. When we ship to customers, generally I think the 3-4 days (or whatever) of transit time might shave about 2 weeks off the lifespan -- but we're using this in automative applications which are likely less "critical" than the aerospace uses for which this Hysol was originally developed. Just my personal guess...

    I think as long as you use it before the expiration date, you'll be fine.

    Box of fun just showed up. I popped the Hysol in the Sub Zero until I can get to it maybe I can sneak in some time this weekend, not sure yet. Wife says we are busy this weekend! :-(
    Now she tells me!...
    But Honey, I just got my weekend activity box in the mail! ;-)

    Almost forgot to say... what a nice pack job Daniel and thank you very much for getting it to me so quick! I was a bit worried about the transit time with the Hysol. Great job...as always!

    OK I got the bad arm out and the hysol or whatever the factory uses was all gone. I just pulled the ball joint out of the arm with my fingers. What remained was like a dust that I could wipe away with my finger. No grease inside the cups either just dry with residue. Does anyone have any grease recommendations for when I put it back together. Is wheel bearing grease good enough or is it too thick? What is the closest thing to the one mentioned on the bulletin that my local auto parts store might have?
