My 2a 1971 has the extra welded taper on the passenger side of the rear axle as you look from the back it is the long side of the diff, i read somewhere it was welded on because the castings were weak on the 2a.

Any way, mine has just rusted away , axle is fine , chassis is fine. I took trusty angle grinder to it tonight and chased it back to the axle to about 6 inches from the spring hanger where it is solid again.

Will this go through mot?, my theory was that if it was looking rotten it would fail if however it wasnt there at all it might not!

Dont off road so cant see axle is particularly compromised strength wise (rust hasnt been doing much for last two years to strengthen it)

Words of wisdom please and thankyou.

personally i would replace the bit that is missing with some 3mm plate or swap yer rear axle for one that int rotten
 
yer it were the military pattern strengthened axle casing, the std ser 2 is not got a box section running across it, either replace it with angle iron welded on point to point as the forces to stretch angle iron far exceed the bending strain of the axle, or just leave it if its tidy , specialy if the landy is not heavily loaded. mines the same, :) mot is ok
 
Thanks all
Think i will leave it it looks tidy and the casing has cleaned up nicely a bit of wax oil will leave it fine, if it breaks will replace it, might remove the brakes to save me a job, if its not there they cant mot it after all!!
 
a note of caution to anyone who does weld on a replacement stiffener ... as I did ...

I cut one side off a section of 3mm box to make my stiffener, copying the original. my small MIG welder only goes up to 130a on a good day, so I dropped it in with a fabricator up the road to give it a good buzz.

it came back beautifully welded, but the heat input all along one side of the axle had put a very slight curve on the whole axle.

not an ideal situation ... would have been better off without the stiffener ...!

how much ****in power !! :eek: the original strengtheners wer only welded every 4" and allowed to cool between welds keeping the tension of the axle casing normal, as a fabricator should kno ;)

dunno if yer can see from the pic

the force needed to stretch box secion is so big it just dosent need fully seam welding te tension / pull is from the drain plug point ( well pretty close) to the foot of the spring bracket so as long as its welded at each point its more than enough
 
Yeah - the forces work a bit like the wires on a suspension bridge. ... don't need to be joined all the way down.

Was a little disappointed with the fabricater - he's class 1 Lloyds coded and oughter have known better. Anyway I straightened it without too much bother - the curve was very slight.

This was for a widened series axle - cutting the long halfs off two series axles to make a wider one with the diff in the middle. as such it needed to be a bit stronger than the original as the projection beyond the spring perches is longer. Had to move the spring perches too ...
