Re: Anti-roll bar bushes
The Alfa design presents some problems:
1. Dropping the subframe (to access the bolts) means the rear suspension alignment must be checked - expensive.
2. The bushes are bonded to the anti-roll bar, I think. This is OK when the bar is assembled to the subframe and then the subframe is fitted to the car. When the car is lowered to the ground the bushes are not overstressed.
3. The bushes are enclosed on the outside by welded brackets. You have to drill through the holes in the brackets to release them.
Unbonded bushes should be tightened with the roll bar in its normal ride position.
Because you cannot access the bracket bolts with the subframe in position the bushes will be overstressed when the car is lowered to the ground.
Ken's method overcomes all these problems.
