Subframe Bushing - Alignment ?

[mobiledynamics]

I don't think it's required but I figuered I'd run it by you guys.
Changing out the subframe bushings on our X5. I don't think it's involved in the rear geometry at all, but wanted some opinions....

New tars on it....$1600 on it...
Last alignment was done around this time a year ago, and she feels fine *no alignment needed *

Will I need to do a alignment after I change these bushings out

is it necessary maybe not; depending upon how bad the bushings are. How much will the suspension geometry change when you swap those bushings IDK. Its really your call on it.

It is stated an alignment is needed anytime a suspension components is loosened or replaced. Do I align every fwd vehicle I change axles on. No I do not.

The X5 subframe bushing bolts locate the subframe not the bushings.

Also subframe bushings have no effect on tire wear. There are other parts on the rear of the X5, when worn, that can ruin a set of tires.
