At nearly 95k miles, the original front struts on the '98 LeSabre (F41 w/ rear ELC) are starting to show signs of weakness (front gets jumpy on hard braking, starting to lose tracking on bumpy roads, a little too much "bounce" on the bumper "push test"). I am hoping to get another 3-6 months of life out of them before replacing them.

Rear original air struts seem to be just fine. All other suspension parts are OK, as far as I can tell (visually fine, no leaks, creaks or noises, no other ride complaints).

So suspension guys, from searching the forum, it seems I want Monroe Sensatrac part number 71822 for front struts. Is this right? Is there a better option?

Supplemental question: Are these front struts a shop job or DIY? I'll be getting an alignment either way, of course.
(Note: Last time I changed struts was on a 97 Altima--using 2 sets of Autozone loaner spring tools, I felt like I could have been killed any moment, and those springs were WAY less "beefy" than the Buick'* )

71822 sounds right to me. That'* what I got. And for front struts you should use the same.
The only other better option I can think of would be Monroe Reflexes, but they are not available anymore.

Front struts are easier than rears from what I've been told. You could do it yourself with the right tools. I saved my self the hassle of dealing with old rusty bolts though.

Ahhh..I thought I had that backwards.
