Nissan traction bars

Post by GT50 »

My Nissan D22 year 2000, the rear rubber bushings wear out very quick it has been this way since new. My idea was to put traction bars I have seen the ones that have rubber bushings in the front as you brake or accelerate the car it will compress the rubber bushings there are two, hope that l made myself understandable. Has anyone tried this? Putting nylon bushings the pick up gets to be very hard. This is a everyday car.

It seems like this company is aware of the general issue. Have you ever contacted them?

Also, if the bushings that you have tried in the past are too hard, you might look into purchasing material with a lower durometer rating and have custom bushings turned on a lathe. Superpro may be able to accomplish this easily?

Kevin, thank you very much for the information. I never contacted this company, they are to far and the price to send it to me would be more then the items. I have a lathe just need the material which is not being easy to find.

Casting polyurethane rubber is pretty easy, I've done a little bit making some custom prototype vibration isolators at work. My favorite vendor is www.smooth-on.com. They have a good selection and lots of how-to videos. Vacuum degassing is almost required but they are cheap on ebay or you can rig up a simple apparatus with a paint pressure pot and vacuum pump from harborfreight :-). Or just the pressure pot and pressure cure them. www.mcmaster.com has some hardness comparison kits, basically a keyring full of 1" squares of samples over a wide range of hardness, if you need some guidance. Making a mold for a simple tube shape is easy, or if you have a nylon or stock bushing in good shape you could pull a mold off of it then cast polyurethane copies. Again, browse the how-to videos for ideas and contact smooth-on for suggestions.

Thank you for everyone help. Well... I know that quality has a price but for a leave spring, is there a real difference between Nylon, POM or poliurethane to make a bushing?
