GBMUD Posted July 28, 2009 Share Posted July 28, 2009 If I were looking at a Salisbury axle, not attached to a vehicle, how would I be able to reliably check it was not bent? Chris Quote Link to comment Share on other sites More sharing options...
mmgemini Posted July 28, 2009 Share Posted July 28, 2009 Put it on axle stands. Look along the length. You'll soon notice a bend. Well we did with te last one I saw bent. They also tend to throw halfshafts out when bent.... mike Quote Link to comment Share on other sites More sharing options...
Hybrid_From_Hell Posted July 28, 2009 Share Posted July 28, 2009 Stand it upright on the flange on a level lump of plate Place a straight edge across the top equal overhang each sidfe Measure from the end of each of the overhangs to the base they should be equal, if not its bent Do this to check axle bend back to front and up / down if that makes sense as casings can bend either way Nige Quote Link to comment Share on other sites More sharing options...

Would this be a quick check or more involved? Marc. Quote Link to comment Share on other sites More sharing options...
BogMonster Posted July 28, 2009 Share Posted July 28, 2009 If it has wheels and tyres on you could check the tracking with either an old-style tracking bar measuring the distance between the sidewalls front/back and top/bottom, or a proper wheel alignment setup if you can access one.

Fitzy Posted July 28, 2009 Share Posted July 28, 2009 The way the diff places do it here in aussie is to get an old diff centre, pull out the spider gears, and place a long piece of solid bar though the stub shaft through the diff centre and out the other stub shaft. the bar needs to be held securely by the diff centre. this will show up any distortion in the housing and then the housing can be heated up on the appropiate side to shrink it back. A bit of mucking around to set up yourself but you could hire it out for others to use? Quote Link to comment Share on other sites More sharing options...
Paul Posted July 29, 2009 Share Posted July 29, 2009 Maxidrive Mal simply suggested putting the axles in the casing, engaged with the side gears. Move the outer end of the axle in a circle at the limit of the freeplay, around the inside of the housing tube. Unless the diff end splines are trashed, you should not be able to make the outer end of the axle touch the inside of the casing tube in any direction, and if the tube is straight, the axle should maintain the same clearance all the way around. If it's able to get closer to the tube on one side, then it's bent. Mal also suggested that most Salisbury casings he's ever encountered (and that would be rather a lot) are at least slightly bent from the factory. Howver, this doesn't seem to cause much of a problem, except when fitting Maxidrive lockers. Straightening a bent Salisbury is pretty easy, and doesn't require much more than brute force, like this: Yes, I know that's a Rover axle, not a Salisbury, but the method is the same. The hydraulic porta power was used to keep tension on the casing whilst the Maxidrive mounting block was being welded on, but straightening the housing is the same setup, with just a few more pumps on the hydraulics.
