wash your armpits and put deodorant on.
You ,don't just live with it...
Remove the plastic caps on the Astra wiper arm. There is a nut under the cap, remove it. The arm will now slide off of the splined shaft.
You're under arms are exsessivly rubbing together with sweat. Along with the hair folicles that grow under their. A meal of bacteria grows along the under arm and eats away the sweat and oil giving off a groteque odor. Same things happen with bad smelling feet.
mine its like a U shape on the arm, press a small button under the plastic housing and pull the wiper towards the arm and it should just slide off, and to remove the arm, theirs a large nut on the end of the axle to the arm. remove it and the whole arm should fall off
look where the gear comes through the body, the arm has a small lock under the hollow part of the arm where it connects to the gear, release the lock and pull on the arm.
under the cowl, remove wiper arm assembly, remove cowl, remove windshield washer resvior (sp) and you will find it
Wash it.
Use febreez
Under wiper arm flap is a grub nut, Undo nut and use a Wiper arm removal tool (there not expensive approx £10) Remove Arm and Replace with New
At the base of the arm where it attaches to the wiper transmission, remove the little black cap (just pry it off ) and tighten the nut under there. A 15- or 16mm socket should do it.
Your best bet would be to purchase a Haynes manual. Remember... safety first! Jist: disconnect brake lines,remove hub cap , loosen lug nuts, remove cotter pin and 36 mm, jack up car and secure on jack stands, remove wheel, remove drum brake, remove emergency brake cable, remove the clip holding brakeline and disconnect brakeline from the trailing arm. remove lower shock mount, notch the trailing arm and spring bar to ease realignment, remove driveshaft. remove 17 mm Allen nut on trailing arm and the three bolts holding trailing arm to torsion arm... remove trailing arm. Put a jack under the torsion arm and jack it up until the arm lifts slightly off of the stops. Remove the four bolts and the torsion plate, remove the outter bushing. IMPORTANT: (do at your own risk) do not get any part of your body underneath the torsion bar while in this position... you could get hurt. With a prybar, pry the torsion arm past the stops and slowly lower your jack. Once the torsion arm is under no stress, use an angle finder to find the angle (will help with reassembly). Remove the torsion arm and inner bushing. Remove the torsion bar. Assemble... in reverse probably... haven't done it yet. Hope this helps.
A deodorizer remove unwanted smells.
