Update on Urethane tranny mounts. WOW!

Well - I made another set of tranny mounts for my wagon, and installed them this morning - all I can say is WOW! It's like driving a whole different car - no more jerkiness when accelerating / decelerating - just pure smooth power. And also no vibration that I can find - they are working just as you would imagine brand new mounts should work. I would reccomend this mod to EVERYONE with an older soob, as every tranny mount I have seen has been shot. The driveability has improved dramatically.

I can make these if people want me to - but you can make some yourself just as easy, and pretty cheap. The tube of urethane is like $14. I'll charge $25 a pair + shipping if you guys want me to do some.... might seem expensive till you price new ones ($55 EACH), and it takes a couple hours of my time for each set - have to pull em from the JY, then clean, prep, and put the urethane in em...

sweet,

 

I have a gehetto fix involving a old seat belt in place right now.

I have been tring to work up a method of doing just that.

 

did you remove the old rubber?

 

thanx good find tell us how they hold up over time.:burnout:

I removed the old rubber that was loose - but there isn't a lot of rubber in them to begin with, and what was there, and still well attached I just left, and covered with urethane so it won't deteriorate any more. They should hold up just like any urethane mount or bushing would, and as the racing and off-road communitiy know.... they are nearly indestructible. Once fully cured, they are like a hockey puck - very dense, and hard to even bend by hand.

some of my honda buddies have done this to their motor mounts. i was considering it.

Yep, that's what I found, too. I posted about doing this on my car last year, and now have 1000's of K's on the mod, still working great. I did mine in place (on the car) and used duct tape to block one end of each mount. Highly recommended. I also made sure the tranny was centered in the mounts and tunnel before injecting the goo, and let everything set while held in place.

Call me obtuse, but I NEVER would have thought of that! And it's a KICK A$$ idea. I can't wait to do all my bad mounts on the new ride;)

good plan. i'v bought new trans mounts from dealer, and thought they seemed "loose" feeling. thanks for the details todd

GD, if you can make the EA82 mounts by next weekend, are you going to the NWR rallycross? Bring them along and I can pay you then. Otherwise, send me an address and I can snail mail a check to you and pick them up next time I'm in Portland. My email is edrach@spamcop.net.

Hey GD, if you have the time could you do me a favor and put together a small how-to together explaining the basic's? This is something that I think needs to be in the USRM.

 

I noticed lately that my car has been bucking alot more, some of those mounts are exactly what I need :)
