Just installed Monroe 171685 Quick-Struts and MA822 Max-Air Shocks on my Deville. I took it for a three-mile trip and it rides a little bouncy. Is that normal for these shocks?

I wll be getting an alignment this weekend.

Also, I have a question about the holes on the Monroe brackets vs, the factory struts I took off. Both holes for the bolts on the factory strut are exactly the size of the bolt that holds the lower part of the strut in place. The top hole on the Monroe is the same but the bottom one is wider as if it were made to adjust in or out. I put it back as close to where I thought it was but wondered why they would do that unless it's to make the strut fit more than one vehicle.

I've attached an image I found that sort of shows the elongated lower hole.

If I didn't get it exactly right I'm assuming the alignment will fix that??????

thanks again for your help.

no -
in fact most people say the ride is too stiff -
compared to the old - worn out - bouncy struts and shocks -

The top hole on the Monroe is the same
but the bottom one is wider
as if it were made to adjust in or out.

exactly - it allows for a little adjustment -

I put it back as close to where I thought it was
but wondered why they would do that
unless it's to make the strut fit more than one vehicle.

during new production - it saves a LOT of time/money -
NOT to require an alignment -
and with all brand new parts - it's very close -
as the saying goes - close enough for government work -

by the time the car needs new struts - 100,000+ miles -
there is a LOT of "slop" in the front end -
the slight amount of adjustment helps get it closer to "perfect" -

If I didn't get it exactly right I'm assuming the alignment will fix that
correct -

Thanks for the replies. I'm getting it aligned today and we'll see how it drives after that.

I did realize I posted in wrong forum after the fact, but didn't know how to move it and didn't want to double post. Jayoldschool, thanks for moving.

I did not tighten the top center bolt assuming it was tightened to specs. I'll check the torque on that and see if it should have been tightened.

Alignment fixed ride and everything. Tires were way out of specs and probably added to bouncy feeling. Runs smooth.
