Rear crossmember bush
« on: 01 December 2018, 19:00:51 »

Been queationed before i know

But rear crossmember bushes

Are carlton or senator ones the same ... saw a guide somewhere once saying carlton different

However a lot list same busb for omega senator and carlton

Just asking as seen senator ones have no voids and wilk be alightly stiffer due to this so if will work i will fit these

If not guess std omega bushes be ok and i found these on ebay item 401170164798

Pair cheap if correct for.omega

Slightly different.

If you're after performance the you need much deeper pockets...

If you want to stiffen it, fit Monaro polys. If you don't, fit Omega ones and call it done.

Senator/Carlton ones are a different shape, although they fit, they work loose in short order.

As DG says, Carlton ones work loose really quickly, which is why many of us run polys.

Why don't you want polys (cost aside). Its a myth that they harshen the ride, they just take it back to the ride of a new rubber bush...  ...which will feel firmer if you're used to shagged bushes.

Probably the price difference.
Polys £150.... Rubber £30.

To some it might be,  I'm quite happy with mine,  I like the unpredictability and sofa like handling, that STD bushes, and worn suspension gives, I've got poly fronts..

I replaced rubber ones twice (both new one sets lasted two years) before I ordered polys. So if you gonan keep car several years, it's not so big difference to change to polys at this point.

I GO with good std replacement and fit poly inserts. (ill make myself ..)

i disagree with poly harness statement.. ive used polys on most of my cars and can always feel the NVH increase slightly . but not a lot.

Std ones replaced will make it better anyways as its on original ones now and done 136k and 14 years old ..
replace again for genuine gm or like quality and should see the car out. but if i make the inserts or compression bushes to compress rubber slightly get slightly stiffer bush in turn and no increase in nvh..

thanks anyways guys.. but yes price of poly rear mounts i doubt ill be buying poly ones.

You're missing the point...

Standard ones fail because the bonding fails between the rubber and the steel structure, allowing water to corrode the structure, which in turn causes the bush to fall apart...

No such problem with the poly ones, and something that an insert won't solve.

Indeed wont fix what will happen .. but standard ones last long enuf .. and insert will cost nothing as i make myself so they will be stiffer than std bushes but not as stiff as poly (as vpids will be filled with insert) thus sgopping it tearing as easy and wont increase nvh

Done 9t before on other cars im ok with this thanks.

Not paying 150 for poly mounts

Obviously didn't read first post then ... question was do Carlton / senator ones fit as have no voids so a little stiffer than omega ones

That's all

Got answered they don't so that's fine I'll go std replacements with a poly insert

I drove about two weeks with poly's and it was driving me nuts, to much noise and vibration.
Handling was awesome but not the nvh so I switched back to the original ones.

Just asking why also these Pedders EP1168?
