Hey guys,
I've just replaced these with some new bushes, and have checked all the bolts and that everything is tight.... however, when I get up past 55km/h the steering wheel shakes and shudders like crazy. Its predominantly when veering toward the left... Do they have to be reinstalled with load applied to the car? With these new bushes, do they need to be tightened until you can't tighten them anymore, regardless of the split pins position within the crown nut? Any advice would be greatly appreciated.

Edit: The bushes replaced were the 'outer track control arm'

Tighten up until you hit the crush tube on the bar, with weight of car on wheels, to 15 to 45 lb. ft. torque.
But, if the old ones were worn, then you prob. need a wheel alignment anyway as the the geometry under load (i.e. when driving) is now diff due to no slackness. |

Hey mate,
Thanks for your reply. I've tightened them up to the workshop manuals specified 61Nm and it seems to be a little less violent now. Is the 'crush tube' the aluminium insert? Or am I mistaken. I'll do a basic allignment tomorrow and see how she goes. Thanks again!

Crush tube OEM was steel (which can rust to bar and be a pain to get off), with some poly bush kits including a stainless replacement. These sleeves normally rust (in 40yrs) so need replacing with the bush.
The crush tube is a sleeve fitting over the steel bar, giving you a shoulder to push the large washer up against to a gain a 'correct' and constant level of compression on the bush. Without the crush tube, the susp forces would mash your bush in no time and give very interesting handling I'm sure. So ....you have bar from front of car with a big washer, TCA bush with crush tube inside, another big washer (that doesn't go over washer - sits against 'shoulder'/end face of crush tube), castellated nut with split pin. Apologies if this seems overly simplistic. I've only ever seen steel or stainless crush tubes. |
