Replaced the original saggy old front Macpherson's today, the new ones are fantastic, front end is up about 80mm and the vehicle is now nice and level as the rear got done a few weeks back.
Found the squeeky bit in the front as well, seem a common complaint of noisy front ends on Colorado's and dealers have a hard time finding why, I found the why and the easy fix is replace the front struts with decent non genuine units.
Here's the old flogged out Macpherson mounting plate, the shocky bolt had flogged the hole on both sides and would do it again unless you use a better unit.
If you want to DIY I would suggest getting the struts mounted as I didn't and could only get to within 15mm compressing the spring, these new buggers are strong and while my compressors managed the old ones and other stock springs it couldn't do the new jobs, so raced up to the smoke and spent $25 getting them set up ( or buy bigger compressors at $150 plus nah ) once the spring and shock were together then we could get things going but the normal spring/shock combination is a damn sight easier than these mongrel Macpherson struts...............
With no manuals available for the Colorado it's a bit of trial and error.
Strut out.
New one in place......
.............Not as hard as I thought it was going to be and the Spring mob said if I had a Ranger or BT50 I would be spewing as they can be a big pain.....................So all the suspension is now upgraded and it was about $1300 all up but thats doing it myself, I had quotes of $1,600 to $2000 for it to be done in a shop.
So
@Smergen and
@boots33 if you have noisy front ends here's the fix...........also nearly fell flat on my face when I jumped out the first time, bigger step needed.
