Pictures of how I fixed the Swaybar Link slop and lean with liquid urethane bushings on my 87-95 Nissan Pathfinder.
Sloppy steering and leaning turns. Scaring my wife and making my little boy carsick.
I have read that this is caused by worn out bushings in the sway bar links
(Nissan calls them alignment bars instead of sway bars. But we agree that a link is the little metal stick on the end).
New urethane bushings should fix it.
I would not pay the dealer or even ebay for new ones. It would be around $35 for new ones, front and rear.
Nuts to that. I paid $30 for 1 lb. of 80A liquid urethane. 1 lb is less than a pint.
The liquid urethane is a two part kit from Forsch Polymer Corp.
Two parts of the A (Base) mix with one part of the B (Activator).
A Base, B Activator? Why must they confuse me?
The instructions say measure by weight, not volume, hence the kitchen scale wrapped in plastic.
I thought I would make a long urethane cylinder, then cut it into individual bushings.
So I rolled a piece of paper into the size I wanted. I made the bushings 2.5 cm od, 1 cm id, 1.5 cm thick.
And to make the hole in the middle, another roll of paper, stuck into an old bushing to center it.
Then I mixed up a small batch of urethane. I used .15 lb A Base and .075 lb B Activator.
And I poured it into the paper cylinder.
After about 4 hours I pulled it apart...
and peeled the paper off the outside.
It had only cured for a few hours, so it was still soft. So I cut it then.
I wrapped a piece of paper around the outside to get a straight line to cut to.
I cut the urethane, but I did not pry the pieces apart and break the inner paper, because I was afraid I would damage the soft bushings.
After 48 hours the bushings were very hard. The instructions say they should be 80% cured by then.
So I cut and ripped them apart, rough and aggressive, and did not damage them.
The new bushings look nice. They are very round and fairly even. Way the hell better than the old ones, anyway.
And installed, they look good, and ride very well. No squeaks. Is there a huge difference in handling? I guess.
I would probably have to change the bushings on the bar itself to really feel it. Those look harder to make. Maybe later.
- Next I sold out to make 02¢
so I can fulfill my lifelong dream of owning a 1986 944 with blown head gaskets.
But no minivans!
- Then I finished my beer.
