Help Arb Stuck

[RGT100 0]

HI

I have a 306 disc axle and am trying to remove the ARB i have removed the end cap from the one side and striped the thread in the other

my problem is i have removed driver side end plate but the shaft is solid i have bashed the s*ite out of it but it hasn't move at all am i missing somthing here from the guides it looks as if it just pull out?

Can you not put the end plate you removed back on and push it out the other end, just use a rear caliper bolt or alike and copper grease before winding it in.

hi

its siezed on the other end and i have stripped the thread so i can not get it off

is it a case of keep hitting the ARb i only ask as i am starting to mangle the end of it

[j_turnell 136 3 Cars]

So you have removed one end plate correct?? Are the threds fine in that? If so remove the bolt, put the end plate back on, undo the 13mm on the other end plate and wind the bolt back in to push it out.

I have stripped the threads in the other end cap while trying to get it off

[j_turnell 136 3 Cars]

Right im with you now, in which case, gently prise it off with a pry bar to try and break the seal a little and then smack the other end with a copper hammer or alike as not to damage the end of the arb. If you can get the bolt to go in atall, wind it in a few threds then tap the bolt up and down to help break the seal on the arb.

Also with the 13mm undone the end plate wont turn at i tried to move it around to free it

[RGT100 0]

I'l give it a go

So is it the end plate thats seized not the ARB?

Also im going to need another endplate as there are no splines left in the one i took off can i get one of any 306 or are the splines different for the different thickness ARB's

[RGT100 0]

finally got the end plate off bent like hell but off

 

BUT the ARB is still solid in place is it just rusted in

How do i go about getting it out now is a normal occurance or am i just unlucky

 

Also the ARB dosn't sit smack in the middle of the trailing arm its slightly to the side

[jord294 92]

it sounds like your bearings have collapsed and the axle was suffering camber issues before you started stripping

 

from experience o/e trailing arm shafts only had approx 30mm i/d, and the arb is 24mm

 

so if you did have camber, it is quite possible that the old bearing, grease, dirt etc has got into the tube and solidified

 

with the off centre angle of the arb going through the smaller end of the trailing arm shaft, this is why your having trouble removing it

 

hope you can understand that ^^^^^^

So how do i go about getting it out

[jord294 92]

So how do i go about getting it out

 

if what i said is correct, i wouldn't even of entertained stripping it in the first place.

 

only way to do it really, is to take the complete trailing arm, torsion bar, and arb out at the same time

 

BUT that could be a task in itself

 

portapower FTW

so im really best off taking it back to the breakers and getting another

 

What i am trying to do is get a reasonable axle rebuild it and then replace the one on my hdi but if it is as bad as you say best of taking it back

But as i have taking bits apart are they likley to take it back now i have part taken it apart

[jord294 92]

very much doubt they'd take it back

 

i take it this was gonna be your first beam rebuild?

 

if it helps, i can supply you rebuilt beam?

[RGT100 0]

I wouldn't be able to afford it buddy i know how much they go for

That reason why i was going to rebuild it over a couple of months

I ll see if i can get it swaped in not ill take the trailing arms and Arb dont want to take any more apart intill i can see if i can get it swaped

is there any thing that will else that will cause the arb to be on the piss

Also i made some meaurements

hub to hub

Top to top 1450mm

Bottom to bottom 1460mm

Whats the standard camber on the 306 as thats a 10mm camber inwards at the top on just the hub would be moore if the measurement was on the wheel

[RGT100 0]

How come with all that camber the suspension still moves up and down freely with my weight on i would of thought it would of been solid

 

It was solid when the ARB was connected but now ir bounces up and down nicely

of you have the end plate off one side, the ARB will just pull out of the other side, undo the 13mm bolt.

 

may need to tap the end of the ARB to break the seal as the small yellow one tends to stick quite well.

[RGT100 0]

Right i have took the Axle back and they gave me an exchange unit the only difference is the beam is black instead yellow is there any difference

Yellow one came of a HDI-Dturbo

Black one came of a hdi

Are they different or is it just painted to look better on the D turbo

 

The one on my car is black anyway i have 20mm Torsion bars and 20mm ARB i didn't measure the yellow one

[jord294 92]

tbh, i relly don't think the colour matters for the crosstube

 

i'm baffled now as to your plans for the beam

 

is it to upgrade the beam on your car (what car is it by the way?)

 

or just to replace a tired beam?

 

i know the 306 xsi/gti uses 20mm torsion bars and a 24mm arb

 

iirc the 306 hdi estate uses 21mm torsion bars (same as xsara vts) but not sure on arb size

[welshpug 1,655]

DTurbo hdi is the same spec as xsi and gti6/rallye being a sport spec beam, if its from a straight HDI it's likely to have something like 19mm or 18.9mm torsion bars and a thinner ARB.

[RGT100 0]

My axle is very tired and need replaceing squeeking Etc 185,000 on clock

so i got a replacement axle to rebuild and lets face all the 306 axle now could do with new trailing arm bearings

also as im taking it all apart if i come across a Gti Xsi in the breakers ill take the Torsion and AR Bars

With the case of torsion bar thickness is thicker the better

Ie Would 306 Estate 21mm Torsion bars be better than 20mm Gti even thought the GTi is better handling

I assume ARb is thicker the better from the seach i did

 

for future info are Front Hdi Lx springs the same as HDI Dturbo front springs or are the gti springs

Example If i put Gti/xsi/Estate torsion bars in would it be best to fit GTi/Dturbo Springs

[jord294 92]

i think the noticeable difference will be the 24mm arb from the xsi/gti

 

but from experience, the 21mm torsion bars do make a difference

 

it all depends on what you want to do with your car

My replacement beam has 20mm Torsion bars and a 20mm ARB so if i fitted a 24mm ARB essentially it would be a GTi Rear beam?

I would like smooth ride with good handling but i know i would have to sarifice ride for handling

I assume the ARB dosn't affect th comfort

I don't want rock hard suspension How much harder would the suspension be with 21mm Torsion bars or is it minimal for the amount of improved handling?

The car Will remain at standard Height

The reason i ask is there is a hdi estate in the breakers near me and he quite cheap as you have to remove the parts your self
