2010 Buick Lucerne air suspension

[Wardonkey]

I just replaced the air suspension on the rear of my 2010 Buick Lucerne that has 101,000 miles. My mechanic says i dont need an alignment but others are telling me I should if it slightly altered the ride-height. The old suspension was "working" but had to reinflate the shocks more often as they wouldn't hold air. After 101,000 miles thats expected. But anyone have any thoughts on the alignment? Or perhaps just get it checked at the very least?

If your old air suspension was still working, albeit leaking, then just changing the shocks *shouldn't* effect the alignment. The shocks simply raise and lower the rear end to a preset "trim" height. As long as you didn't disturb the position of the height sensor, and your rear end sits the same now as it did previously, you'll be fine.

That being said, having your alignment checked at 100k miles certainly wouldn't hurt. Bushings sag, parts may have flexed over time, etc.

Thanks. I did have it aligned 6k ago when I got new tires
