Window Weld Rear Subframe Bushings

Anyone done this yet? Mine will be out this week and I was wondering how much of a difference it could make.

I wouldn't trust WW for suspension bushings. I don't think it has the shear strength to last very long in that application, especially if you put any serious loads on the suspension.

Should only make the stock bushings stronger imo. I can totally see them not working as well as real poly bushings, but I figure it has to be better than stock 19yr old bushings.

Unless your worry is that maybe they'll mess up the bushings permanently somehow?

I upgraded my rear subframe and "mustache" brace bushings to the poly ones that Tuners Nation sells. When I was removing the stock subframe bushings, I saw how badly worn they were- to the point I could almost knock them clean out with my hammer. IMO, the factory subframe bushings are a lost cause. The bushings on the mustache brace wouldnt benefit much from the addition of WW either, IMO, because youd only have a .25" thick layer of it over the stock bushing. Maybe you could try filling the gaps in the subframe bushings with WW, but theres no way it could ever be as good as the poly setup and may not even cure very well since youd really have to pack it in there thick...

I've had phenomenal success with 3M Windo Weld. It's far more durable than people give it credit. I've had my front motor mount (an others along the way) filled with Wind Weld for over 5 years with not even a crease, crack or flake. The drying procedure isn't as nightmarish as people claim, either.

A question I do have for you is that since all of our suspension bushings are solid rubber/whatever to begin with are you certain that the subframe bushings are in fact a bridge type like the motor mounts? Otherwise I just don't see how you will be able to effectively apply the Windo Weld. As mentioned above, spreading it on like peanut butter on toast will not provide you with results.

Here's a thread to give you an idea of how some of the bushings are set up.
