hi guys i think i'm looking at front torsion rods or lower arms, but when braking particularly if i'm going 5/10mph when it's most noticeable when i brake suddenly/hard it feels like something moves on the front end and springs back when i release the brakes, i noticed it more today when i had right lock on.

 

i've got poly bushes already on my torsion bars so am i right in thinking these have failed or the lower arms have cracked?

Hi, i dont know if its the same thing but i experienced exactly what youve mentioned and it turned out i had a crack in my lower control arm - i took it to Jeff at Zedworld at the time and they welded it up and it was spot on after. Ive sonce changed it but may be worth looking at as i was advised mine could have snapped at any time

yes i did mention that in my original post there was an issue with them with poly bushes fitted. looks like i know what i'm doing tomorrow lol

quick update on this, i've been out this morning checked both front lower arms and there seems to be no obvious cracking around the tension rod mounting bolts, i did however check the bolts before removing them and both passenger side mounting bolts had loosened, and one drivers side, i can see where the nuts have been moving/rubbing against the bottom of the lower arm, only by 2 or 3mm however. so tightened them back up with a long breaker bar this time. hopefully this will fix the issue only a few miles will tell if they come loose again i shall look at replacing the stud/nuts with bolts & nylocks nuts

Are your tension rods and control arms stock? I you have Midori style suspension components with solid or rose mounted joints, then this is endemic of them as they can work themselves lose, another reason why I hate solid joints.

Here is a good read.

Hi Si everything is stock apart from poly bushes in the torsion rods, possibly an issue caused by those, or maybe when the rods were fitted by a local they were not tightened correctly,i've only started to notice this after fitting new proved front discs & replaced the servo

Hi mate - did tightening everything solve your issue? I will be investigating the same issue on mine tomorrow!
