Standard versus polygraphite front suspension parts
« on: January 11, 2010 - 08:30:41 AM »
I am trying to get situated to order the parts to rebuild my front end.

I am looking right now at Moog (Rock auto) and PST for poly stuff.

Basically trying to decide whether to go with one of their kits or just get the poly kit for the control arms and struts....seeing if I can save any cahs by buying their poly stuff and then the Moog stuff for everything else.

But ran into a snag --

The PST site says

"These Bushing sets include Control Arm Bushings and Strut Rod Bushings (if your car has strut type suspension!) We supply 6 Polygraphite® Control ArBushings and 2 Polygraphite® Strut Bushings for Chrysler products.
 
Note: Polygraphite® Lower Control Arm Bushings not available for these models -OE type Lower Control Arm Bushings are supplied. "

Then, for the part number for the Barracuda they say :

"Barracuda - Polygraphite® Control Arm Bushing Set 1964-74 
SKU: CRSP00887
Description: Set includes: 6 Polygraphite® Control Arm Bushings and 2 Polygraphite® Strut Bushings
Price: $100.00 "

HUH?

If the lowers are only available in standard, why do they say they supply "6 polygraphite" control arm bushings?

Now thats a thought.   I actually have a set of lower bouncers that I bought a while back already....

Do you get any squeaks or anything?  I have used Energy stuff before and its straight poly, right? I have had squeaks before...so I was considering the polygraphite for that reason.

I found part numbers for the control arm busing kit and torsion bar boots....but none for the strut arm bushings.....or upper bouncers.....

They seem to have the strut rod bushings in their big kit, but in that kit I end up buying stuff I dont need......

Did you find poly strut bishings elsewhere or did you have to go with rubber?

Also, I guess no one makes a poly lower c.a. bushing.....all of the vendors seem to sell only the uppers in poly.

Energy makes the lower in Poly , it is a different part # for the 6 bushing kit , I can get you that # & it is still available
I found the strut bushings in poly from Energy as well

I have part #5-3112G for the upper and lower control arm bushings...is that the number you have?

Would appreciate the # for the strut bushings.

I am waffling on whether to go polygraphite (PST), just plain poly (energy) or good old (moog) rubber.

I did a search on the web for "polygraphite" and numerous references to both polygraphite and polyeurethane squeaking and being too firm....some folks have no squeaking at all and love the ride, others say they squeak but love the ride, others have no squeak but hate the ride (too firm)....there's about as many opinions out there as there are people.  LOL

What I dont want is a squeaky car that has to be lubed all the time or one that is too firm or transmits too much road nose up thru the body.....

I guess the original rubber lasted a while......I am sure the ride will be better with everything new even if its just rubber....

  When installing any bushing it should be tightened up in its normal ride position. This is more critical for poly as the standard rubber has more give. Every poly bush I have seen squeak had been tightened with the weight off and in some cases with too little or no lube.

Sounds like good advice.

Will do that when I reassemble.  I have pretty much decided to go Moog.

Why not go Poly-graphite?  It's not significantly more expensive and you'll never have to replace these pieces again (unless you buy rubber and want better handling)

Well, I was considering polygraphite or the energy poly.  Actually struggled with the decision.   I certainly dont wnat to have to replace this stuff anytime soon.

From past experience, I know that the energy stuff can really squeak even if lubed when installed.    The price is attractive on the energy stuff.

But potential for squeak is making me shy from the energy stuff.

The other issue is that both the polygraphite and the energy poly  are going to be stiffer....I know the energy stiff is a LOT stiffer.....I really don't need to feel every bump in the road as some folks have suggested will happen.

The moog stuff claims to not be regular rubber but some sort of poly stuff that wears longer and gives a little better handling but doesnt sacrifice ride.  I guess we'll see.

Plus, I figure the car came with rubber and they lasted this long, even if they were worn.....this isn't a daily driver or a race-track car so I figured Moog would be fine.
