'94 Pathfinder, Stock for now!
Hi Scott. The original centrelink has had the tie rod end's replaced.
1.) On the Pitman arm side a hardened polyurathane bush has been custom made to fit which pivots on a M10HT bolt.
2.) On the idler arm side a hime joint has been used. This side required a bit of machining to suit the new hime joint. Again fixed with a M10HT bolt.
3.) Both fixtures are greaseable via the grease nipple on the side of the casting.
Basics of a Hime Joint
The Hime Joint comprises an annular shaped socket. The socket encases a freely movable ball shaped member with an included opening in the center, straight insert, which is mounted and secured within the included opening of the freely movable ball shaped member of the Hime Joint. This embodiment is attached to the ball shaped member by a bolt passed entirely through the embodiment which is secured by a nut on the bottom.
The idea behind using a flexable fixture (hime) on the idler arm side is to prevent premiture wear and tear on it's bushes under extream loads when the centrelink twists. The force used to get transfered into the idler arm, now there are only horizonal forces directed through the idler arm from steering inputs, which is originally what the Nissan engineers would have designed for.
I used a fixed poly bush on the pitman arm side because it is allot stronger than the idler arm and has no wear and tear issues. One question I think will come up is, How long will the poly bush last before it needs replacing? I can't yet answer this. I've been using it for about 2 years in moderate to extream conditions, but infrequently, about 20 trips over that time. I was told the bush is quite easy to replace. If I was to help supply the product I think I would include a spare set of poly bushes or at least offer it.
I have used this setup on some serious off-road trips and it is amazing the differences it's made to the whole driving experience. I used to hate venturing out wondering in the back of my mind will I get a little over excited (which is what it's all about) and bend the tie rods today!!! Or will my trip fall short of its destination for the same reason and disappoint the convoy....
Hope thats enough information for you to sort something out. If you have no luck, let me know and I'll make a few phone calls and see if I can get one made again.
