Im about to order a polygraphite bushing kit from PST and i just need to know if the bushing with there kit will fit the RacingBeat swaybar? I read somewhere on here that the bar takes a special size. In addition, i need to replace my idler arm(s), Do i want poly's for that too or should i just get the regular rubber ones?

Thanks!

cool, are the ones from VB any good?

The RacingBeat swaybar is larger AFAIK. The PST bushings supplied will probably not fit the bar. Ask RacingBeat for those particular bushings instead. There is one idler arm and other than the grease boot there is no rubber in the assembly. You have two choices when it comes to the idler arm, you can replace it (it's cheap enough) or just replace the bushing inside (even cheaper).

Hmmm....... are you maybe talking about the tension rods? If so, yes, get the poly bushings for those.

Usually its the hard plastic bushing that wears. Plastic =soft, steel= hard. Unless yours got bent somehow, just buy new plastic ones. I got the VB ones. They were beck arnely IIRC. work fine, last long time.

I dont have the bar yet, im still trying to figure out what to order. Do you know of another bar that the bushings might fit on? Or should i just use the urethane bushings it comes with?


Sorry, i knew that. I was going to bed last night when i wrote that, and didnt catch it until this morning. But anway, in this picture i took out of a factory service manual. It looks like there are 2 idler arms? If im going to replace the one should i just do both of them? Sorry for the huge pic.

Rx7carl

Misprint. Item 4 is the pitman arm. Dont **** with it.

thanks, i see that now. Funny how a VB catalog can be more correct than the factory service manual.

Carl which parts were you talking about here? Alot of stuff got bent when i had my accident. So it is possible that it bent something in the steering as well. Its sloppier than it was before and sometime the wheels will pull, but the steering wheel doesnt turn... So im pretty sure i need the idler arm.

They were some kind of green plastic.

Those bushings are significantly cheaper than replacing the whole idler arm unit.

5 bucks for the bushing 30 for the idler arm.... eh, whatever. When you buy the whole assembly you get the added advantage of getting a new ball joint.

i think ill just get the whole assembly from VB. Seems like the best deal. I dont want to take anymore chances with old parts. Thanks guys

Inittab, speak in english man! whats AFAIK?

Rx7carl

AFAIK= As Far As I Know..........

Dude there is NO balljoint on the idler arm..............

inittab

okay, it's a knuckle.. I rod end.... you know a universal swivel thingy

Rx7carl

Nope.................. Only the pitman arm has a ball joint on it. The idler arm is solid.

OOOHHHHH DAMN. you got told!

bubba211

idler arm is solid technically, but still has 2 bushings. The PST front sway bar fits, AND you get a deal when you buy a front end kit and the sway bar (what i plan on doing very soon)

they have sway bars that fit our cars?!!! Dammit, i JUST hung up the phone with them.

inittab

I bought one from VB and it had one and so did the one I took off the car.

I just did the PST kit with RB bar. PST bushings do not fit the 1-1/8" bar. The kit came instead with the bushing for the stock-sized bar. They offered to give me a generic 1-1/8" replacement bushing, but couldn't guarantee it would fit my car's brackets ('84). End bushings work fine; it's the "D" bushing that's the problem.

I ended up using the polyurethane (not polygraphite) bushing that came with the RB bar. Car's not on the road yet, so I can't comment on squeaking, which is why I went with polygraphite to begin with.

Rx7carl

Ok, I wont argue.

Thank you, that was exactly the anwser i was looking for. I ordered my Graphite bushings from pst this morning. I kinda figured that was what i would have to do. So im just going to hold off on the sway bar right now, until i get springs and illuminas. The only thing i dont get is if they are both 1-1/8" bars. why doesnt it fit?
If you bar does squeak, may i recommend wraping that section of the bar in teflon plumbers tape? I heard that works better than any lube, and it doesnt wear off.

I called back and asked if they had a sway bar i could add to my order. They guy on the phone (Rus, maybe?) said that they do not have one available for our cars.

bubba211

why is it their catalog then? they have a front 1-1/8, and a rear 3/4in. each $119 when you buy with a front end kit. for 79-85 mazda rx7. guess they just stopped carrying them. that sux

stevehilde

The RB bar and the one PST sells (sold) are both 1-1/8". The stock bar is, I think, 23 or 25 mm. The bushing included in the kit fits the stock bar. The generic 1-1/8" PST bushings are the correct inside diameter, but they may or may not be the right size (outside) to fit inside the D-shaped stock brackets. Since I had the RB bushings, I thought it too much of a hassle to exchange for the generic PST ones.

Thanks for the teflon tape idea.

Will the front end kit advertised by PST work with an SE? I don't know for certain whether or not the bushings differ between models. TIA for anyone who knows.
