    Default cracked tierod attach point

    What would cause a crack in the attach point of a tierod on the steering knuckle. A while back work was done on the steering rack that had to be removed and re fitted.

    Are those not hammer impact marks. Exuberent whacking could do it as they can be boogers to get out.

    It could also be an expansion pressure fracture

    Thats just plain rubbish quality and cheap manufacture. I don't recall ever witnessing a failure like that in my life. I have beaten those for ages to release a ball joint that has been in place for years. Left both sides, you could access, flattened out, but the cars run to this day with that arm in place.

    Next time you install a ball joint like that, give it a bit of grease on the shaft so it pops out with minimal effort next time.

    Wrong size hammer used. Hammer was too small.

    Thanks for inputs. The knuckle is still OEM from Jeep. Also though was caused by hammer blows, but was also told, over tightening causes the taper to put too much stress resulting in crack.
    Also for sure ball joint removal tool not used.
    Tried TIG welding, but Aluminium type material would not hold the weld. So waiting for "new" part.

    The abuse with the hammer probably left damage that was a stress riser for the crack to start. Over tightening on the refit accelerated the stress crack. People should realise that there are specified torque values for the different nuts and bolts on the vehicle. A big hammer isn't the correct tool for this type of job.....

    Whilst aluminum alloys are pretty strong they don’t have the same ductility as steel or ductile iron (which is commonly used by many manufacturers on suspension components these days).

    Combination of circumstances / events, the pin is tapered and that will put a strain on the ring but it should be able to withstand it. Beating it with a hammer is par for the course even with a ball joint removal tool. Best way is to take a big hammer and wallop it do not play, if done right one shot usually does the trick.

    This is where the probable real cause of the failure came in, Aluminium is another pest of a metal, hit it with a hammer and it gets harder to the point that it will get brittle. Panel beaters back in the day when Land rovers had dents repaired and not panels replaced used to beat the panel and every so often take their blow torch to heat the area to anneal it.
    I think this joint was hit with a too small hammer and needing a few blows to get it to release and this hardened the ring just enough to split.

    To anneal alu is easy, take an ordinary bar of soap and draw a line on the area that needs to be softened and heat that area untill the soap line turns brown.

    was taught by my Dad to use two hammers: one hammering and with a four pound held opposite and against the tie rod to absorb the shock.

    one or two good blows is all it takes.
