If you put a two piece 73 bushing set with the collar on a early strut rod you will move you LCA's back 1/4 inch. the collar is built on the early struts and the nut tightens to that. With the 73 collar on the early bar you will not get the pin in the bar in front of the nut and cupped washer. The later bars are shorter then the early bars flange to flange comparison. To allow the room for the two piece bushing set with collar. If you want I can post the difference but some of you would have your own reason why your incorrect install is correct anyway. Do like the last guy I tried to explain this to. cut the bushings and the collars to fit. If you look close in the dark maybe there is a line to cut them to make them universal fit for all years.

They do make a two piece bushing set for the early bars they are alot smaller and get no collar. They also are not as stable as the one piece.

It would not hirt to do what you say and put the bushings on cup facing the rubber on the 73 up. It will help the bushing life . It will also make the front end alot less flrxable and help handling. This was only done to alow more movement and a softer ride. The performance 73 up suspension they faced the rubber to give the car a firm suspension . Here is a pic of a 73 340 front suspension that was never taken apart since new. Notice the cup faces the rubber. newer kits tell you to face them away . the bushings are alot larger then originals .

regardless of what it says on any cup, i have, and will continue, to put mine on so the bushing is cupped. that is why my bushings last tens of thousands of miles

Rubber has a lot more give than urathane. rubber bushings cup the bushing. Urathane bushings cup away from the bushing.
 
Since I've got an Amazon Prime account I just ordered some Energy Suspension pieces.especially since I'm leaving for a 8 week training program for work and I'll need to have this car ready to go as my wife's backup vehicle if anything goes wrong with the truck while I'm gone..

According to PST's warranty...Lifetime warranty...I was the original purchaser so I shouldnt have an issue getting it warrantied

http://www.p-s-t.com/Warranty
 
I think the originals were put on to cup the rubber......I think the after market ones(Moog) were made and stamped to go the other way.... I'm still confused!
 
Cup that rubber and make it last while tightening up the front end.
This is what I did with my frontend.

In my opinion, there is not enough movement in the front of that strut rod that there would ever be a concern of the cup edge hitting the k member and limiting travel. otherwise they wouldnt have kept the design for so many years. with the cup facing in, the cup will split the bushing causing premature failure and from what i see in the OPs pics, that is exactly what happened here. had the cup been installed the opposite way, that bushing would still be there and working the way it should.
 
I talked with someone at PST. Since they are unable to find the sales record in their computer system, they are unable to warranty any items.

I was OK with that, until I asked the customer service Rep if could take additional photographs of the components for verification and email him...the response was "What would be stopping you from taking pictures of a friends car and claiming that its yours? If we did that we'd be sending out hundreds of boxes a day for false warranty claims. They're only 20 bucks man, just buy another set."



I was too taken back to respond, I was thinking to myself he must be an idiot because I (like most people) don't have time to go thru all that hassle for a set of 20 dollar bushings and now I've spent so much time on the phone and not working that I might has well of bought another pair.


He told me that unless I have the original receipt, there is nothing that they will do. Thats somewhat understandable, but the rep made a BAD judgment call because now I'm going to blast them on every forum I can find.
 
Every stone-stock unmolested Mopar I've ever seen has the cup embracing the bushing. To face it the other way is to concentrate the load on the center of the bushing, not distribute it over the bushing. If we think about how the arm moves, the cup follows the arc of the swing, and compresses (and retains the compressed side) of the bushing during arm travel. See below. The cupped side out forces the bushing away from the shaft and tries to split it apart! Think how a chisel or an axe works: You're concentrating the load on a small area.

The FSM backs all this up.

Besides, if it was in Mopar Muscle I'd discard it on premise. I've yet to read anything technical in that mag that's consistently correct or even interesting. Like how they recommended tossing the ballast resistor for stock ignitions? C'mon, seriously.

I don't know what the writing is about. Possibly parts robbed from Transverse T-bar world (I would expect poor engineering from them...). I've never seen an unmolested Mopar with those "this side out" washers, anyways.

A quickie drawing with bushing in blue and the washer in red. See how the cup tries to capture the bushing?

exactly. the real pain the *** is when the inside cup is put on the same way and you cant see that it has come apart. and the only way to rectify this is to back the control arm out enough to get the strut rod out and replace the bushings. i have never tried this without popping one of the ball joints out of the spindle, but non the less, these are parts that should be done right the first time so you arent tearing the front end apart every 10k miles.

I apologize if you feel that our Customer Service Department did not handle your issue in a satisfactory manner. But unfortunatley on all warranty claims warrant a copy of the invoice for Proof of Purchase. Unfortunately our paper records only go back 5 years and the Rep was unable to look your order up in the computer with the shipping zip code that you provided. If you can find your invoice please scan and send a copy to me and I will be more than happy to send you out a replacement bushing. As for the way that you were treated by the rep. I will be pulling the phone conversation as they are all recorded and look into that matter seperately. If you have any questions or concerns please feel to call me or PM me.

Thanks

Please stop spamming so many boards with your BS :wack:
Its a 20 dollar aftermarket bushing, if you want it to last 30 years get a set of moog bushings and install them right. No need to post about this on even random off-road forums. JEEZ
 
You can only cup them correctly with the original style tapered washers and bushings. The radius washers should not be put on in the opposite direction to cup the bushing . The inside diameter is smaller then the outside of the bushing.

And the problem shouldn't be PST's. They only lasted about 4 years when these cars were new. And then the washers were installed correctly.

being that the web is anonymous..no offense taken...but I did take the time to give a huge props to Bunn Coffee Machines and Haeger Stoneware products when they displayed extraordinary customer service.

The fact is (and I wish I had recorded it) the P-S-T Customer Service rep may be an alright guy, but he was a HORRIBLE customer service representative who insinuated that I was even lying about the car I've got.
 
Washer was installed PROPERLY

I just yanked this off the car, cleaned it off, and snapped a pic

i will never install a strut rod bushing cup with that side to the bushing. asking for failure. i dont know whos dumb idea it was to dictate that side in, but thats *** backwards in my opinion ,every photo shot we have posted clearly shows them the other way.

Out of curiosity I just went and checked mine and the cups are facing out...66 Plymouth Valiant. However, I don't know if they were ever replaced...probably so....but will find out in a couple weeks or so when I redo the front end.

All this because you feel entitled to free bushings after your 8 year old ones failed......
 
ok so i asked the boss about this... he said it depends on the year...

and the reason they are different is the actual shape of the cup its self...
