Urethane FILLED Subframe bushings

[525ikicker]

im very intrested in the bushing idea.... i have looked at prices for new subframebushings from racingking and for the price i think its worth the try for urethane bushings.... now the question is how long will the bushing last?
i hope for longer than 2k miles, if they do i will consider trying this.
real cool

I wonder if this would work on part #8 on an e30 http://realoem.com/bmw/showparts.do?...61&hg=31&fg=05

What's your take on the stuff now, after it's had awhile to cure?

[Russell]

directional stability is much improved going through curves as it stays where pointed. Straight line wandering seems to have improved slightly. I think it rides just a bit stiffer.

My guess is if the bushing is open on two sides there is more of a chance of the fill material popping out. Also, the more solid bushing is, less impact filling would have.

That makes sense. I'm wondering about using a brand new bushing of the sort that is partly open, then filling the gaps by adding and curing the urethane before installation on the car.

that approach is what many of the euro or Japanese car fans do with many of the bushings, especially motor mounts. Buy new, fill and install. In fact, thats where this idea came from.

After a couple of weeks of daily commute, the charaterstics seems to be stable. better directional control-seems to stay where pointed, LESS wander-not eliminated, possibly stiffer ride, less clunking from the rear. I also have Bruno's subframe inserts which reduce roll a bit. Glad I did. Stillstock struts on rear.

Next I am going to see if my front suspension/steering needs more attention. I have replaced upper thrust arms with Lemforder with 750i bushings, sway bar ends and front struts with stock Boge units. I suspect there is a small amount of play in each tierod, center arm and other bushings. As far a I know, they are original with 135,000 miles

Hmm... I need to do this. What gets replaced back there, what gets filled? I get a bit of a "wiggle" when leaving at anything above light throttle.

See my first post. All I filled was the subframe bushings and did not remove them from the car.
