Alfa 147 suspension arm

My suspension arms have gone on both sides. The arm that has gone is the one that comes from the hub area and goes forward onto the body, not sideways onto the cross member. Waht is this arm called? I want to buy the powerflex bushes to fit.
Is it possible to replace just the bushes on these? and if so how hard is this to do? i just want to know how much time to allow for doing this aswell as the front top wishbone.

Thank you.

Look at this :
and this :
The lower wishbone changing isn´t a job for beginners,remember the outer balljoints aren´t changed when you install new PU bushes,buy new wishbones start with the upper ones,they are the " easy" ones to change,change the PU bushes in the new part prior to changing the wishbone.If the bolt in the upper wishbone by chance is mounted opposite the original mount look at F156.2 you might be able to remove the long bolt without having to loosen and pull "suspension upright" down, if inner plastic lining is remowed like in the foto. There is a "thread" somewhere in this forum I think.

Robbieuk85: Are you referring to the front or rear suspension? Sounds like you are taking about the trailing arms at the back as these go forward from the hub.

Powerflex do the smaller hub bushes not the big fat trailing arm bushes. No-one as far as I know does, so you have to get two new arms if these are weak or split.

Fitting new trailing arms is quick: two bolts into floor area and one on hub end. If you are thinking about replacing the hub bushes they are easy if (a) the old bushes come out and (b) the hub bush bolt is in the right way: nut at the brake disc end. Otherwise the brake disc and backing plate has to come off or you cut the bolt and replace it. There's a how-to on my greenserpent website. I swapped my rear hub bushes to powerflex last year, as well as all four transverse arms (new arms, standard bushes).

Powerflex also do the transverse arm bushes: the pressed steel arms running from hub to central alloy crossmember: 2 per arm, 8 per car.

As for the front, note that Powerflex bushes don't always fit the lower arms in non-Alfa parts ... it's on their site. Apparently some OEM arms have smaller diameter "pins" that the bushes press onto.

Yeh I was talking about the rear trailing arms. Thanks so it looks like I'll be buying 2 new arms!

I already know how to do the upper wishbone as I've done the o/s/f but thanks anyway
