need to change up my VSS relocation on my ford 5r55e SOHC. Post up some pictures and ideas. i had it mounted on the tail shaft of the trans and just had the stock drive line damper machined with slots. but that has to change due to parts availability. looking at solo kit for the transfer case of a bronco. may be able to use that as a start.
 
I made one that fit on the 9in rear axle yoke. Remove yoke and it installed and the u-joint u-bolts held it on. Then made a VSS bracket off the pinion support bolts. I just cut notches in the flat flange i made but it didn't work very well but it was just for CEL and speedo on a manual 01 ranger so didn't effect how it drove just needed CEL off for smog
 
thats sounds like a place it may have to go. the 3rd member takes a beating but..

does it really need to be one? i have a dakota digital gage system that is a GPS speedo. maybe i could have a tunner tune out the CEL? or does the computer need the signal for the trans to work right?
looking at the solo motorsports/DM bronco one. i could probably get it to fit on the yoke next to the center bearing.

I'm not sure what axle you are running but I know some axle swaps run abs tone ring at the wheel end of the shaft so you may be able to adapt something like that onto the axle shaft or backing of the axle flange to keep it out of harms way. It would only read one axle speed but I don't see that being an issue when driving straight normally because tire would rotate the axle shaft at same speed as vehicle unless you're stuck or crawling
 
You can also do what I did on my first race truck to keep carrier bearings alive, because they don't live with a slip in driveshaft and into transmission, was I got a strap style yoke and I drilled and tapped the end of output shaft ol hack n tap style to bolt the yoke on. To do this with existing driveshaft there was some play between end of inside of yoke at end of shaft I cut some tubing to put in so I could torque it down tight. With threat done you could do a vss relocator on trans like bronco's use.

Also unrelated but fun fact about the Solo VSS relocation kit my speedo was jumping quite a bit on my truck and I checked the polarity of the magnets and some of them were opposite and pushed my test magnet away while some attracted it. So I flipped the opposite ones over so all same polarity and now it's ready good as it should.
 
I have a full floater since 1990. current set up is a speedway eng with the aluminum hubs, but plans are moving forward to install a different set up in the rear with all the camburg 2.5 front/rear hubs and snouts i got last year.
is there a way to tune out the need for the one (of 3)vss? i am just going to the junk yard and get a original slip for the trans.

but one idea is maybe just epoxy magnets to the shaft and relocate the senor.

or maybe trump will FU!k with CARB enough and i will be able to motor swap it easy legal.

more ides and what others have done wood be cool to post up.
 
I cant find the information and pictures of where I saw it but someone machined the back of the ring gear to accept the tone ring. Bolted right up. Then drilled and tapped a hole in the top of case to install the vss and it worked.
 
Yeah I've seen people machine 3rd time fit and 8.8 tone ring then mount sensor in housing.

You may also be able to machine a ring like the bronco and machine, the inside of the hubs and press it onto one side on that and mount one sensor on the wheel
 
I know ben has an OBS f150 2wd with 2 piece shaft and he's running the leduc VSS relocation on his and hasn't had any problem he said. Still has slip front and carrier bearing. So maybe curt leduc has one for the trans you're running
 
here is pictures of my old set up and my new slip. i was told before i put this on that there would not be room but after seeing cbrewer22 and installing my, i know i can get a cnc cut part to fit.

but... i will need to drive it around a bit more because at this point, it is not affecting any drivability. may kick a CEL later.

The reason I ask is I'm thinking of cutting out a disk and using a cheap mechanical caliper to use as a parking brake for both my prerunner and crawler, and was wondering how the gear was affixed.

Ya it’s nothing fancy. I had a second one but can’t seem to find it.

Thread derailment engaged. If you want a mechanical parking brake that would work. I cut one out for Mikey to use on his bronco with a go-cart mechanical caliper But he never used it.

If hydraulic would work use something like this i've seen popping up online lately. https://www.ebay.com/itm/3253752887...-83db-9ef7949d29cc|iid:1|vlpname:vlp_homepage
