I've got a spare W-Arm,actually the original from my SRX,and as most people know if you've got any aggressive miles at all on your sled the arm is probably cracked.Well mine is and has been fixed a couple of times finally resulting in replacement.Having inherited the trait of not throwing anything out from my father I was looking at it a while ago and talking to a machinst friend about replacing the broken square tubing with either sturdier square or round tubing.I'm going to take it out to him and see what he thinks but I'd like some input from people that have tried this and found what works as far as thickness(gauge) tubing,type of material(chrome moly,etc).I'd like to fix it for a spare but do it without adding too much weight and keep the strenght.Any welders,fabricators or machinists out there with any ideas?

gussets !
you and your dad should really think about splitting on one of those big dumpsters! than you should tell your machinist budy to copy one and make it all out of alunimun than i will buy one from you.or send me the same size id pipe and tubeing with thicker walls and some 1\4 flatstock for gussets and brackets and i will build you a set and one for me?

where do theses things tend to break is it along the square tubing or is is more by the joints and welds? i have a proaction and have not broken mine yet and am curious as to where the prolem lies in these arms. fabriacting one would not be that difficult, i would first try one out of aluminium before going to any exotic metal, i think it would do the trick.

they usually tend to crack right by the weld joints in the tubing
cut a square hole on the back side of the lower mount, slide a 8in piece of square tubing up inside it, first drill holes through the outside, then spot weld it in place along the length of it. then just reweld all the factory welds.
now fixe the problem that broke it. the bushings in your shock are shot, use rubber or bearings. do a search on my user name, ive wrote about this before. also, rebuild the lower mounts and shim them tight and use grease fittings. then your w arm problem will be gone and your front shock will actually work for a change.
