Yeah, what does MBA know? He's only been stranded for hours at a time and lost days of wheeling waiting on D35 repairs... from either wheeling with someone w/ a "super" D35 or because some punk broke and clogged the trail for those of us smart enough to have "fixed" the issue from the get go. Not to mention the scores of snapped axles from street driving on 235s...
But since you persist, even though you've been advised against it...
Pickup a heavy duty retractable "mechanics" magnet. It must be smaller dia. than a quarter and long enough to reach your chunk down the axle tube. Buy a quality magnet cause you'll wear out the first 5-6 times it gets used... you'll be needing it to drag the broken axle splinters (usually snap where it necks at the splines) out of the side gears. Also, better start stocking up on spares, grab a handful of spare "C"-clips if your 35 uses them, a plastic pan to catch the gear oil you'll loose when dropping the cover, a gal. of 90W & an empty for the old oil.
There, helpful enough?
