    Question Heim Joints on Adj Torque Arm

    How long would the heim joints typically last on an adjustable torque arm? I'm hearing some noise (a knocking sound) that sounds like it's coming from the rear axle. Gears and rear end are all fine. The only thing I can come up with is the end joints on the TA. Its got about 75k miles on it. Has anyone ever had to replace these? Or, do you just buy a new TA?

    Any help is appreciated... comments welcome too.

    Some noise is just the nature of the beast for hemi joint or aka rod ends. Personally I just replaced all of mine when I hit 40K miles on them. I was not having any problems, but wanted to prevent any issues from occurring. It also would greatly depend on what type, material, and brand your hemi joints are. Because like all parts some higher quality parts well last longer before replacement is needed.

    Thanks vetteemt. The TA on my car is the adjustable one by UMI. It has 3/4" QA1 rod ends. I was just wondering how long they typically last since the noise I'm hearing has gotten progressively worse over the last year or so.

    Is the out side housing silver or black? Either way if they are getting nosier it might not be a bad idea over the winter to just replace them. They also make rod end silencer cups that help quit them down some and also help keep grease in them and dirt out of them, I highly recommend you install them if you are replacing the hemi joints.

    They're silver. Can I ask where you purchased your replacements? Are better versions available? If I'm going to replace them I might as well put better ones in. Also, I would assume that something on the adjustment setup uses a reverse thread. Would that be the heim joint shaft?

    All of my suspenction is from Spohn Performance, when I talked to them when I was getting ready for replacements they stated that the silvers were the better joint.
    Being that you have UMI contact them www.umiperformance.com or Sam Strano at www.stranoparts.com, either on should be able to get you replacement parts.
    Yes there is one part that is reverse tread, but I can't remember which. You would be best just to ask them when you call for parts.

    I replace all my rod ends as part of a regular maintenance schedule.

    For a street car they need to be change more frequently in general based on driving style, pavement shape, pot holes, etc.
