Tech: Valley Springs Install
|Raising the rear of the Montero
Installing the Valley springs are the best way to improve departure
angles and rear articulation. Installing coil springs could not be easier. You will need a
few basic hand tools including a pipe wrench, a pair of jack stands, and a pair of jacks.
A Highlift jack and the stock unit that comes with the Monty will be sufficient. The best
lift point on the back of the Monty is in the middle of the bumper where the hitch pokes
out. I recommend cutting that flimsy little strip of metal below the hitch off, since it
will get bent trail riding anyway and helps the departure angle. Remove the spare tire and
chock the front tires then set the Highlift under the hitch. Lift the Monty with the
Highlift until the rear tires barely come off the ground.
|Removing the lateral rod
Once the tires clear the ground place a jack stand under the frame on
each side of the Monty just forward of the sway bar mount. Place a jack under the pumpkin
on the differential then unbolt the lug nuts and take off the rear tires. Take out the
right side (passenger) lateral rod bolt and both lower shock mount bolts. Lower the rear
end to the limit of the brake line travel. You might have to remove the sway bar mounts
which consists of two bolts at the end of the sway bar. I did not have to remove mine. The
old springs should fall right out. I was able to squash the new springs in the mounts, but
others have needed to use a spring compressor. Make sure you line the end of the coil
springs up to the end of the mount. You will see how the coil is made to sit in the mount.
This will insure it is fully seated.
|The finished product
I had four jacks and used two of them instead of jack stands, but for
safety always use jack stands. You can see the sway bar mount in line with the trailing
arm just behind the orange Mitsu jack . Notice how tight the brake line is. The brake line
on the Monty is in the center of the diff where the least amount of travel is realized
unless the whole rear end drops down. Raise the rear end with the jack under the diff
until the trailing arm lines up with the hole. I had to use a pipe wrench to twist the
trailing arm to get the bolt to go through the mount. The shock mount bolts went in with
no problem. Depending on how old your Monty is you might want to replace all the mount
bushings with poly bushings while you have them handy. Jack the rear end up and install
the rear tires. Use the Highlift to raise the Monty enough to remove the jack stands.
Clean up your tools and enjoy the new springs!
If you have any questions or problems with the install feel free to
give me a ring at the Outdoorwire
Mitsubishi forum. These springs are 15% stiffer for a gain of 2.5 inches of rear lift,
but are designed to compress fully for maximum articulation. Since they compress fully
then they are not made to allow bigger tires, but the Valley springs do handle the
33x1250s BFG MT better than the stock springs.
*Editor's note: This tip applies to all coil sprung models of
Montero/ Pajero, Montero Sport and Dodge Raider.
