A: The Bentley doesn't say so, but in my opinion the car will be on the wheels and the suspension loaded anyway or else it will be very hard to fit the parts. So by default the suspension will be loaded anyway when you do the installation and final torque. It can be done with the suspension but I think it is easier when it is loaded. In my opinion backing the car onto 2 ramps is the quickest way if there is no access to a lift.
Q: Can I tell if the part is bad without removing it to take a look.
A: In my opinion no. It is very securely fastened at the forked end and so I don't think you will see any rotational movement at the bushing end, but maybe some lateral play (which could be a sign of it being bad). However, if you were to unbolt the forked end and slide it up the LCA toward the center of the car so the forks are somewhat clear, you could then try and rotate the bushing end along the long axis of the arm. If you can it is probably shot. [Edit: this is not true in my opinion now. I believe the bushing is designed to rotate that way. I think one way to tell if it is bad is to unbolt the forked end and then see if the ball end rattles around. Or remove the arm, put the bushing in a vise and push on it. If it moves or clicks, those may be indicators of it being bad]
Q: Do I need an alignment after replacing this part.
A: No  [Edit: at least 1 out of 3 of my FAQs were correct when I first put them out... ) |
Hey Steve, thanks so much for this write up! I was on the fence for doing this project and now with your help will attempt it myself and save the labor cost for other wear and tear! One quick question is can I remove the rear trailing arm while the car is on ramps and the suspension is loaded? I know space might be tight but I'm more concerned if the trailing arm is vital to the vehicle not falling on my head hahah! Thanks again for the write up!
