Ahhh very good. Glad it's sorted

Yup! They said they were going to check the fitment on a diff case before they send me the parts.Ahhh very good. Glad it's sorted
there has to be a burr or burrs somewhere kicking the crown off line or something then mate,Well, back to the drawing board. I got the new gears in the mail and have the same exact issue with binding. All I can think to do now is take the diffs completely apart and start over.
EDIT: After starting over, and trying everything I can think of, I am sending the diff and housing to Kraken. They are sending me a label to ship it to them so they can take a look at it.
The only thing I noticed is on one of the attempts... The outer bearing on the housing fell out as I was tightening the 4 screws on the housing. I went to slide it back on the pinion shaft and could not (the pinion shaft was crooked after tightening the screws). I had to loosen them to get the bearing back on. I took some very fine grit sandpaper and polished every single tooth on the pinion and ring gear and could find no burs. Kraken is mailing me a shipping label Monday morning, so it may be a couple weeks before I know anything. Even if it is something i'm doing wrong, it would be awesome to know!there has to be a burr or burrs somewhere kicking the crown off line or something then mate,
report back please when kraken have had a look and see what they find wrong ,
it will be good info for anyone else building there own kit,
Hello.Hello all,
It's been a long time coming, and I have finally started building my Vekta! Just have bag A mostly finished. This will be a slow build.
Question: I purchased the aluminum diff housing and there is some binding on about an inch of the ring gear/pinion gear mesh. Will this work its way out while driving?

Edit: I took the diff out and put the other one in, and it spins perfectly with no binding. I guess I'll figure out the ring gear binding when I get to the rear axle.
I actually contacted Kraken and sent my diff/gears and aluminum housing to them. They said the cut on the ring gears was not deep enough. They also said they are getting a fresh batch this week and will send me the new ones. It was a big batch of wrongly machined gears.Hello.
I purchased my Vekta several months ago. This build was going to be slow, and I knew I would take my time. But I have been stumped with the ring gear and pinion build for the front suspension, like in your concern.
Once I install the built diff/ring gear setup into the front diff housing, and hand tighten the bolts, the ring gear will bind against the pinion gear, in a certain area and be exceedingly difficult to turn. You can get past this bind and then it eases up.
Just to cut to the chase, after 2 new plastic diff housings, 2 new ring gears, 1 new aluminum housing that holds the spider gears, and a new Taylor CNC machined front housing, I still have the binding as I spin the pinion gear thru its turns. I have spent countless hours testing, measuring, and rebuilding the front only to get the same result. The moment the bolts on the housing are hand tightened fully, ring gear binds as it spins. If you look closely, you can see the ring gear having lateral runout, and there are no adjustments that can be made. Remember, these are new ring gears as well.
The moment I loosen these bolts, the bind diminishes considerably. Using power tools, I am able to spin the pinion gear forcing the bind on the ring gear, hoping it would wear itself out, like a break in period. But that runout I mentioned earlier, it actually causes the front suspension to wobble as I use the power tools to simulate real world driving.
I bought this car from DDM, and they have been helpful, but also stumped. I have delayed continuing the build until I figure out this problem.
Any thoughts?
