Hey all. I have a question about metal integrity. So upon removing these Lower Control Arm shafts on my Valiant I somehow boogered the threads. These are the shafts that the control arm rides on and it they butt up against the torsion bars in the rear and go through the K member in the front. So the front bolt on which I boogered the threads is the only bolted part. Is it gonna be as strong if I re thread it? Or have I compromised the integrity of the metal? Thanks in advance.
Run a die down the threads and see if they clean up. If they do.... Run with it. Sent from my Moto G Play using The H.A.M.B. mobile app
DO NOT thread "critical" suspension components with a die as this could be a fatal error. Generally, manufacturers used thread rolling tooling for these operations. Google "thread cutting stress risers" then report back with your findings.
Use a thread file to clean it up, they are square shaped with the thread count stamped on them,they come in American Standard and Metric. They also make rethread dies they just clean the threads without cutting like a normal die does. You can take a nut and saw 3 cuts across the head and you put it on like a die and it will clean up the threads. Hopes this helps Frank
Thread file, But it depends on how bad of a Bugar you created. It looks like the high points are driven down and that decreased the OD of the shaft. Cutting, filling, tapping won't increase the size back.
Or get new ones, not very spendy. http://p-s-t.com/series-220315-greasable-control-arm-pivot-shafts.html
$109.00 sounds pretty spendy to me. I wouldn't trust anything that PST sells.... Had too much problems with their stuff and they will not warrant anything. Sent from my Moto G Play using The H.A.M.B. mobile app
life of self , family and friends is way more than a measly $109 bucks . MOOG offered them a few years ago I think I spent $45 ea for them ( mine the threads stripped off completely it was rusty ) , find a older part store with a catalog or look up a Dodge A body up to 1976 for it , as for PST , rebuilt many a car with there stuff and had no problems ,most of the problems I heard of was people not using the right grease on the poly parts and it squeaks and binds like hell and not use the right torque specs . .
