MG MGB Technical - axle strap failure

This is my "new" axle strap failure after only four weeks of service.

Not a hint of reinforcing cord. All rubber.

Now have a set from the "strapping lad" that should last forever.

yet another example, of many, of modern rubbish rubber parts

They've been like this for a while now, so much so that Moss US are supposed to have changed their supplier and have a test rig to check each batch. Where did you get them from, and I hope you have complained? In the UK at least one supplier has stopped these (at one point anyway) following complaints.
Paul Hunt

it would be nice if all stopped selling and buying the other rubbish rubber parts

last month, again, another set of tyre valves had to be replaced this is the second time for me and the valves were from two entirely different suppliers and about three years apart

potentially there could be a lot of these valves fitted to all sorts of vehicles on our roads now -

Once this quality failure hits condoms we will be in even more trouble!!! Still the population explosion will compensate for those killed by failing tyre valves, brake hoses etc..*****!!
Allan Reeling

4 weeks? that is positively ancient - the last set I fitted didn't even survive lowering the axle!

I am heartily fed up with suppliers that don't give a damn about the quality of the parts they sell ...

Steven-
How about telling us the names of the I-don't-care-about-anything-but-my-profits vendor and the sleazeball manufacturer so that we can all boycott their junk products?
Stephen Strange

It's the principle of it - Here in the UK the "Sale of goods Act" allows us to return cr*p like that. Trading standards will chase the vendors who don't play the game. It's important we don't let them get away with it. Steven - telescopic dampers obviate the need for the straps.

" telescopic dampers obviate the need for the straps."

Can they take the shock of the axle rebound if you leave the ground? I wouldn't like to put that to the test given that the manufacturer would expect a strap to be there on the MGB ... unless they say straps aren't required. Maybe you can do away with bump-rubbers and pedestals as well.
Paul Hunt

I'm with Paul on this.
Straps are pieces of rubber/canvas and are supposed to be tough and support the axle when it's hanging. Your dampers are quite expensive components, best isolated from "end of travel" shocks and loads.
Allan Reeling

Paul,
You make a good point but if you fly your car, the shockers take the strain before the strap and I hope to have a safe landing before it gets to the bottom of its travel. Bump stops ?? .. I tow and they are needed !
Roger W

" the shockers take the strain before the strap "

Only if you do land before the axle has finished dropping. If they are supporting the axle and not the straps when the body is jacked then the travel of the dampers is incorrect for the application.
Paul Hunt

Steven, If your local lumber yard uses polypropylene straps with metal clips to secure packs of lumber these can be used in addition to the naff rubber bands! I made mine a bit longer than the unsprung axle strap, and secured it using cable ties.
