Lower suspension arms (aftermarket or oem equivalents )


Recommended Posts

So I’ve seen a few topics on here where people have mentioned about needing or doing their lower suspension arms, some people say they’re easy and if you’re like me unlucky or you’ve been done by the parts manufacturers here a little guide/ illustration to show you what to look out for and to show why they can be an absolute pain 

 

So here’s your typical inner bush really giving up on trying to keep it together....

Always start by trying to undo the balljoint  first as that way you can keep the pressure on it to undo the nut, if you’re doing it on your driveway place a jack or stand underneath the balljoint and lower the car onto the stand or raise the jack underneath to increase the pressure to stop it from turning when undoing the nut,  if like me the split pin decided to make thing interested you’ve got a few options, clip the excess of split pin and just undo the nut because the split pin will be made out of a way softer metal and won’t damage the thread (nut is a 22mm) and then either drill it out carefully or use a punch and hammer! Or a combination of both, or you can waste your time trying to pry the split pin out which you may aswell just send it to a garage to save your time, I always opt for cut the tails wizz the nut off then drill and tap out takes 5 mins

So don’t be afraid if you can’t get the pin out you can always get a new one after,  so after got the balljoint nut off and the rest of the pin out, release the pressure off the balljoint and it should pop out next undo the 17mm nut and bolt for the shocker, the 17mm nut and 5mm Alan key for the a/r link and then 19mm nut and bolt for the inner bush

 

congratulations the old one is now out yay but no time to celebrate

Before even considering to fit the new arm check it to the old one as you’d be surprised with what companies get away with sending out especially the cheaper ones, as seen in the picture (sorry I didn’t get my uni degree for taking @&@ pics) the recess in the new arm is about 4/5mm larger than the oem, this will cause you a massive ball ache as it’s done for me in the past, the nut will bottom out and not tighten up correctly and then the arm will knock like a jehovas witness. I don’t know why or for what reason but I’ve 6 sets of these arms now and most have been the same when bought offline! But fear not because I’ve suffered so you don’t have to!

If you make a washer to fill in the difference your troubles will be no more! 

i asked my boss to use his lathe to cut down a boron washer as it’s much stronger than the tinfoil washers I have in the garage, granted it will take a bit of time but if you prepare you can adapt and overcome bear grylls style! also after opening these washers up I checked they fit well, bare in mind they don’t need to be snug, the balljoints tapered and not going anywhere and the nut has a built in washer anyway

Drop the washer in and check it fits inside the recess, then offer up the arm out your bolts on hold the arm up so it’s at about 45 degrees the prime the inner bush ( you don’t have to but I’ve been taught it’s better and prolongs the life of the bush) right the bolts up seat the balljoint in the arm and tighten that nut up with the washer sat underneath! Should tightened up really well and now unlike me you don’t have to go home crying to the mrs because you’ve had a bad day working on your bloody shed that she told you is a money pit! Zhou can tell her to swivel because you’ve planned and overcame and she can keep her opinions to herself because she drives some German halfbreed! Just make sure to protect your knuckles unlike this idiot here! (Sorry if you’re a bit squirmy )
