New improved spindle lock nut kits

If you've ever had to fight the awful bending lock washers on the trail or even in the driveway you know what a crappy design it is. I've fabbed up these kits to replace those lock washers once and for all. This is the same basic design as Dana and Warn use for the tried and true Dana axle spindles. The washers are 13 ga lazer cut using the same ID and OD dimensions of the original thin metal washers. The inner nut is jigged and drilled then a hardened pin is pressed in. Installation is easy and repeatable hundreds of times. The inner nut is installed, pin out, and tightened against the washer/bearing to pre-load spec then slightly backed off. The lock washer is installed to align with the pin. If it is alignment is slightly off you simply loosen the inner nut until the pin/hole meets. Install the outer nut, torque to spec and you're done. No prying, peening, hammering out and old washers ever again. The kit comes with 4 inner pinned nuts and 4 lock washers. You reuse your inner nut as the outside nut (it usually isn't scarred from chisels or screwdrivers). The first time you install these you'll wonder why Land Rover never thought of this!
The initial production run was for 6 vehicles. One kit is already sold. Additional runs are planned in the next couple of weeks.
Each kit is $90 including free shipping USPS within CONUS. PAYPAL gifting is the preferred method of payment. Contact me for shipments out of country to determine additional shipping rate charges.

I didn't consider the early style but a production run shouldn't be difficult.

Nice idea but you need to lock the outer nut.

you need to patent that sucker and get these on the market with an RN/AB type distribution.

No, you do not. The torque will hold it in place. This design has been used by most major manufacturers since the 60's without any outside locking methods or incidents.

I was still curious about this since LR has always provided for locking of the outer nut. I looked up installation instructions for the Warn version of this for Dana spindles. They provide a torque spec (85 to 135 ft-lb [Dana 28 and 35] or 160 to 205 ft-lb [all others]) that is a good bit higher than the LR torque spec of 50 Nm (37 lbf/ft). It might be worth considering whether the LR spec is adequate to retain the nut without the original locking means. I don't think 37ft lbs will hold it. If it were mine I would be torquing the snot out of it. If I were selling these I might do some destructive testing and specify a torque that is some percentage of the yield figure.

Also I noticed in the Warn lit that they offset the hole pattern so that when you flip the washer, it moves the holes 1/2 the spacing distance providing even more adjustability for a more precise bearing preload. Are you doing that with yours?

EDIT- Also found this. A Warn version for D35 that includes a set screw to the outer nut.

In any event, cool product, good luck with it.

The next run will have the holes slightly offset for that purpose. In reality, it isn't really required. The Dana-Spicer version is the same as mine. The reasoning is the lock washer has some play on the spindle. When the outer nut is tightened the washer and inner nut rotate slightly towards higher bearing preload. If the pin and hole do not line up you just rotate the inner nut slightly looser and proceed to torque the out nut. I've run Dana axles for years in my old Chevy truck, the original IIA hybrid with the Dana 44 axles and my '96 F250 with a Dana 60 axle. My lastest version of the IIA (should I ever get to finish it) uses the D44 outers and the same spindle nut kit. In each case, I've set pre-load, installed the lock washer and tightened the outer nut firmly (no torque wrench). I've never had an incident of failure to hold or have I ever heard of one among all the guys I've known running these axles. As for the Dana 35 axle, the spindle is only 1.5" vs 1.625" which is actually significant. Even then, Warn dropped this spindle kit some time ago and uses the same basic setup as the D44 and D60 today.

We just installed a set of these on a '99 DI while upgrading the rotors and calipers. The owner was very pleased at how fast it could be accomplished. The inner nut has been double pinned to eliminate the concern that MM3846 had regarding pin shear. To get these out here the price for the set is dropped to $75 shipped by USPS while initial supply last. Kits for the earlier lock washer are coming soon.
There was concern on another forum, as this one, that the outer hut could come loose. Here's my reply.
- There is no need for the set screw. The jam nut is torqued to 135-150lbft. It won't come loose unless you've possibly had complete bearing failure and everything explodes. Dana-Spicer has seen no need for this extra step ever. Warn once did it for the D35 but they decided the cost wasn't justified either. If it would make someone happier I could produce the outer nut with 2 set screws for an additional charge. You could drill and tap your own nut to 8-32 and pick up set screws locally. You'd want to use a cone type set screw, not a point. -

Uncle Douglas, Trey, Tyler, and I saw these for the first time in hand a week ago and they are really a quality product.
Since they are in limited batches, am going to buy one for the coil sprung vehicles and one for the series as soon as the series ones become available.
It will make removal and replacement soooooo much better than bending and replacing those silly tabs.
Did I mention that I hate those bend over tabs!

The use case for this makes this whole new assembly sustainable (you just take it off and put it all back on).
Instead of having to throw a locking tab out and put a new one on every time you remove and replace the hub nuts.
