Subject Vehicle: Generation I (83-91) Montero/Pajero/Raider
This is what was left of my old bumpstop!
For a while now my front suspension has been bottoming out on certain multiple bumps. A cursory glance at the front end revealed that the left lower bumpstop was completely missing! Instead of replacing with the factory rubber, I decided to use a low-profile unit, in order to give my front-end a little more room to flex.
I elected to use a bumpstop from Energy Suspension, part # 9.9102G
Removing the old stopper
What's missing here?
Raise the front-end, place jackstands under both lower arms, (This procedure can be done with the front wheels in place, but you will have better access if you remove them), and remove the front wheels.
Locate the lower bumpstop retaining nut, accessible through a hole in the lower control arm.
Put an appropriate extension and socket up through the access hole and remove the nut. It may need some penetrating oil first. (My bumpstop nut used a 12mm socket)
Remove the old bumpstop, and quickly dispose of it.
Going 'Low-Pro'...
Bolting on the new bumpstop
Remove the rust and dirt from the lower control arm, especially, where the new stopper will sit.
Place the new stop in place
Bolt on the locknut through the access hole
Don't evertighten the nut, or you will risk pulling the new stopper down through the hole, or tearing the stud out of the rubber altogether!
The new low-profile bumpstop, ready to soak up those big bumps!
Editor's Note: For actual gains in frontend articulation, you must remove all droop limiting factors. These include adding longer shocks, longer brake lines, and disconnecting your swaybars. These modifications will affect your vehicle's onroad stability, so use common sense.
