Hey guys, as the title suggests, want to know opinions or facts on the differences between the two. Lemme start by saying I have an ES master set for my EJ. The back is all done, and I was working on the fronts, well i went to press out my upper BJ and bent the shit outta my arm not being careful. So i decided to replace the arms with new adjustable one. I settled with DME UCA. (review to come) Well now the DME is a COMPLETE kit, it has hardware, mounting bracket bushing the whole bit. The bushing are supposedly better quality than OEM, i think he meant slightly harder. So my dilemma is, Do I use my new ES poly bushings in the UCA or the "better" than OEM bushings? and WHY? EDIT: both bushing sets are 100%new

New "better" than OEM

I suggest the es bushings as they are more resistant to damage. Not like they will make ride comfort intolerable either.

The play in those upper mounts is so small...you probably won't notice a difference either way. I'd go with the new and "improved" ones...for no other reason than fresh is best.

I've heard good and bad things about ES bushings but I was planning on running a a full master set as well. I say slap the ES bushings on and sell the others to recoup a few bucks.

I never used either, but generally rubber is a more durable bushing material than polyurethane, especially thermoplastic PU. We don't know if the better unit is thermoset or thermoplastic PU.

The "better" ones look almost identical to the OEM bushings. So what ever they are made of then..... rubber im guessing.

Rubber designed to work hard will almost always be black. The carbon black component is a major part of the formulation to get the properties.

Squeaking means there isnt enough lubrication. that squeaking means wear and tear is happening.


Id stick to rubber for UCA and inner front LCA. poly or rubber everywhere else.

they are fine :')

I bought the kit cause my factory rubber was looser then a ho the morning after payday, and it was cheaper going aftermarket with a whole kit then buy the indiviual pieces...

They have been in about 4 years i guess, and not any problems with them, but my car is almost stock...

(red rubber squeeks, no rubber makes babies ;'D )
sloopy.

I guess I'm the jdm fan boy. But whatever. I agree though that poly is good for somethings and not others.

Most new rubber UCA pivots are not properly lubed if any lube.

If no lube is added they will make more noise the ES setup that is 5-6 years old and lube has gone away.

Tightening the UCA bolts with the suspension loaded is NOT FUN either. EVEN worse when it all backs apart.

Poly will need replaced over time, OEM lasted how long?

A good lube for polyurethane or rubber is plsain simple talcum powder.

Well I tightened the UCA outta the car, with the arm 90* out from the mounting bolts. Which was the position they were in when removed. Also, I did NOT lube the rubber bushings..... should i loosen and talcum powder the inner sleeve?

If you want to be sure it does not squeek do it right. If a bit of a squeek is not a major issue just sprinkle a bit of talk on it.
