When i go over that there is like a contstant rumbling almost like a defect "hjullager" noise it is coming from the rear and am starting to think that maybe it is the aksel,as when i reverse it sometimes jerks backwards.
It is hard to explain the noise but have done my best to describe it.
Anyone know what this can be it is a syncro t3 which i have.

It can be a wheel which is unbalanced, a constant velocity joint on the way out, a wheel bearing nearing the end of its life or the propshaft which needs its cv's renewing and balancing. Loads of things on a syncro make it vibrate, you're lucky if you find one that doesn't. On a diesel it can even be sloppy engine mountings which resonate with the propshaft or cv joints at certain speeds. If the vibration starts at 40km/h then it probably isn't the propshaft, that usually kicks in at around 60km/h.

Hjul i ubalanse, bråk/klunking/vibrasjon i drivledd/kuleledd, utslitt hjullager foran eller bak, gummioppheng i motorfeste løs, mellomakselen trenger nye kryss og avbalansering..........

CV = Drivknute på norsk.
Prop(eller) shaft = Mellomaksel
Balancing = balansering (That simple
)
Universal joints = "kryss" (eg. the four legged part of the joint is called kryss. You'll need the roller-bearings too..) On the T3/T25, VAG states that these joints are non-replacable....BUT they can be changed...
(Rubber) Engine mounts = Motorfester/-oppheng (I gummi.)
Sloppy = (In this case..) dårlige.
Wheelbearing = Hjullager.
Nearing its end of life = nærmer seg utslitt.
Vibrate(s) = Vibrere(r)
Resonance = Resonans (Pronounced as in English..)
Tightening = stramming.
Nut = Mutter
Bolt = "Skrue" or "bolt".
Shim = Skive/shim(s) (Norwegians use shims, plural, even if it's just the one .)
