SD High Steer options - Weld on or machine?
 
Looking for real world feed back on the two options for SD Dana 60 knuckle high steer options. There are several companies offering weld on brackets to convert the knuckles to high steer. Welding to cast can be an issue with breaking so wanting to know if anyone has had experience with this happening or not happening.

The other option is to machine them to bolt on high steer arms. This is certainly a great way to go but more costly. I would ship them off and have this service done for me.

This thread covers every angle of steering for SD axles, https://www.pirate4x4.com/forum/gene...a-60-axle.html

It comes down to, do you have some fab skills or can you write a check. Which can you do?

the only time i would go with a welded high steer arm on a cast knuckle is if it was a crawler that never saw the street or more than 25mph on the trail, other wise im going with machined

When i build mine it's getting machined for bolt on high steer. You should have a local machine shop that can handle it instead of sending out, but also sending it to a vendor here with experience in this service could save you in thr long run... damn it, now I've created a non existent situation in mine own head... send it out or local???

Fordtechguru on here. Runs Weaver Fab out of Redding, CA. Only way to go!

x2 if you want it done right weaver fab is the place to go

Whose hi steer arms are keyed? Looks like the Weaver fab ones aren't?

Are the 4ws arms keyed?

Explain why.

The short answer is that welding dissimilar metals creates a stress concentration. Stress concentration is destroys the fatigue life. Welding dissimilar metals is about the dumbest thing you can do when life and limb is on the line.

personal preference, i like feeling comfortable when bashing through the trail way faster than i should be.

ive seen multiple pictures of broken off welded arms on 05+ knuckles

sure it can be done successfully without failing but its just not for me

edit; i forgot to tell you that you sound like a demanding little faggot

And there's no stress concentration with studs?

After some research I have decided to get mine machined but cant decide between weaver or FWS. Im leaning more towards FWS, alittle cheaper, the arm is keyed to the knuckle and its located above the stock TRE so you can run a tie in kit. All which weaver doesn't do unless im missing something?

Fordtechguru weaver is a long time member here who has contributed much to this forum. That should factor in more than saving a couple of dollars.

Yes. The high-steer arm is keyed into the caliper mount.

Yes but when bolted joint is properly torqued there is a pre-stress in the base material. External loading must overcome this pre-stress before the base material actually "feels" the external load = longer fatigue life.

I'd be surprised if the FWS kit is directly above (and parallel) to the stock TRE. I'm running 99-04 SD knuckles w/ Weaver arms on my buggy and the stock TRE end is angled. Presumably the 05+ knuckles are similarly angled?

I had a buddy who operates local shop machine some parallel spot faces on the Weaver arm and stock TRE so that I could run double shear.

And if you like good steering geometry you'll not use the Ford parts at all.

Ried C`s and knuckles set for 7-8* caster after you`ve set the pinion angle. TR to the cast in arms for Ackerman.

An even better way would be to toss the Ford center and buy an aftermarket center. That way your making the axle fit YOUR rig not the other way around.

Not a fan of the Ford at all...............Yes, its buy in is cheap but the ROI sucks.

seriously? :laughing: :homer: wtf are you bringing up a fully custom axle when guys are asking about what high steer to run on a junkyard axle

reid knuckes and c's are going to cost almost 2k by themselves :laughing:

You are waaaaay off topic, not to mention Dana Spicer makes the axle. Typical chevy nut swingers :laughing:

machined is only way to go. buddy has had 2 weld on's fail. first one i welded and just preheated and mig welded and cooled. second one was preheated and welded with nickle rod by ticketed welder and cooled. both only had few runs on them and failed. hes running machined and keyed now and no issues

Who's keyed arms?
