1. My castle nuts don't fit.
Problem: On some axles the plating fills in the threads and makes it difficult to put your castle nuts on. If your axle did not come with castle nuts then you must use your stock nuts.

Solution: Secure the axle. Put some axle grease (not Vaseline) on the threads. Make sure the castle nut is perpendicular to the axle. This means make sure it is on straight! (See picture below and remember your warranty does not cover damaged threads). Take your crescent wrench and turn your castle nut 1/8 of a turn and back it off, 1/8 of a turn back it off until the nut threads itself all the way down. Remove the nut and wipe off the grease, install your hubs in the normal way.

2. I'm missing some small parts. How can I order them?
If you are missing small parts to your axle you can call us and order them direct. See the picture below to find out the names of the parts you might need. We will help you with the part numbers when you call.

3. My hubs on my X-33 axle won't stay tight.
Let's face it. If you are like me you probably saw how easy it is to install the pin drive hub and threw the instructions away. Let's go back to the instructions and see how to install the hubs and then we'll see why they don't stay tight. The instructions call for us to apply lock tight, torque the nut down to 60 to 90 foot pounds and finally add a jam nut. If you didn't tighten the nut down correctly and the nut comes loose and the hole (bore) in the hub becomes long shaped, and it will shift back and fourth. Once this happened it will not stay tight despite our best efforts.

Solution: Unfortunately the only solution is to replace the hub(s). Please note that if the bore in the axle is egg shaped it will not cause any problems. If the hole in the hub is cone shaped it must be replaced! Yes, you can buy just one hub!

4. My Posi-lock nut won't stay tight.
The Posi-lock nut system is designed to be light and strong. It keeps your axle from moving side to side in your carrier. There are two reasons why the nut comes loose.

In example #1 below we see the inner sleeve is extended out to far. The nut clamping system can't get a good grip on the threaded inner sleeve. Ideally the inner sleeve should not protrude more than 3/8ths of an inch.

The second reason your Posi-lock may be coming loose is that the big nut was over tightened and has collapsed. Remember, using a pipe wrench to tighten the big nut down can cause the nut to collapse and or warp its shape. Get the big nut snug then tighten the allen bolt. On rare occasions you may need to add a washer or spacer to shorten inner sleeve travel.

Solution: Tighten the big Posi-Lock nut until it's snug (not tight). Tighten the allen bolt. ( 17 lbs/ft) Ride quad and re-check the Posi-Lock nut. Re-tighten using a small amount of lock tight on the allen bolt. Check the threaded inner sleeve to make sure it's not out to far. You should be good to go! Thanks to our customers for the pictures!

My Posi Lock nut still comes loose. Now what?
There have been a few cases where the nut appears to come loose despite the fact you did everything correctly on the list above. First, we have to determine that the Posi Lock nut is actually at fault. You can test the nut by taking a felt tip pen and marking the edge of the nut (see picture). Ride your quad for a while and check your index marks. If they are still lined up then it's not the Posi-Lock that is coming loose, but some other component. Bearings are the usual suspect. If the index marks have shifted, then the Posi-Lock nut is coming loose. You can apply some Loctite to the inner sleeve of the nut. Use the blue medium strength Loctite and apply a couple of drops to the threads. Don't over do it with the Loctite ( more is not better). You may need to get the nut off someday! Give the Loctite about 5 minutes to dry so you get full effectiveness. Most people have the red Loctite. If you use the red, apply only one drop!

Some of you have noticed that if you grab the nut, you can rotate the whole assembly by hand! Don't panic this is normal. Remember the Posi-Lock nut system keeps your axle from moving side to side in the bearing carrier.

5. Can I get smoking deals on E-bay?
I spend quite of a bit of time on E-bay. I’ve gotten some great deals there, but judging from the tech calls I’ve received, many of you are getting bad deals. I’ve gotten plenty of calls from riders who bought axles on E-bay and wanted to know what parts they needed to make their axle work. When I tell them it will cost an additional $100.00 I hear cries of anguish! The good deal they got isn’t so good now.  One customer called and wanted to know why his posi-lock kept slipping. Turns out that while he thought he had gotten an eliminator 2 + 2 axle the seller had slipped him a heavy duty axle instead. (ouch!). The heavy duty axle came concealed in an  original eliminator  2 + 2 box. 

Another  issue is warranties. If you are not the original owner you are not eligible to get your axle warranteed!   You must also be careful when you purchase a new axle from a company on E-bay. We do not accept pay pal receipts to verify that you are the original owner for warranties. These receipts are too vague and do not show an itemized list proving the axle is new merchandise. You must provide an itemized receipt showing the name and address of the company you purchased your axle from, date of purchase and a description of what axle you bought! Here’s some advice for all of you that want a good deal.  If you really sit down and think about how much time and extra money you spend trying to get some of this stuff to work,  you are going to end up having a heart attack! The extra aggravation and time spent just isn’t worth the stress, plus the fact you’re taking a chance on losing your money and you don’t have any warranty. The best deals I see are through your dealers who are willing to use their experience and expertise to make it happen for you! 

6. Front Lowering kit for the Honda 450R (04) 20-1008
Due to changes by Honda there may be an issue with the lowering kit not fitting correctly. Honda has changed its front shocks so that there are two small cylinders protruding from the bottom shaft of the shock. These small cylinders interfere with the lowering kit and may cause the shaft of the shock to bend. The problem is due to changes by Honda! The lowering kits were designed correctly when Honda first came out with the 450 R. Durablue is not responsible for replacing bent shocks.

Solution: If you have the right tooling you can cut a notch in the lowering kit to make room for the shocks protruding cylinders. You may also return the lowering kit to Durablue for a replacement. We will pay return shipping only.

7. Bearing carrier Z400-AH
Please Note: The bearing carrier for the Suzuki Z400 has changed mid year. The Durablue Bearing carrier will fit only one of the swing arms but not both. To find out if our bearing carrier will fit your quad please see Figure 49B. If you have the curved rear plate and the mounting holes are the same it will fit. If you have the other swing arm where you have the flat plate in the rear and the wider spaced mounting holes (see chart 49A) our bearing carrier will not work. We are sorry for any inconvenience this may cause. Occasionally a manufacturer will find it necessary to make changes mid year. The Kawasaki KFX-400 and arctic cat models are not affected.

8. Raptor 700 Lowering Kit
We've noticed that the Raptor 700 is offered with special shocks. When you purchase this option, it requires a notching of our lowering kit. You can fix this by using a round file allowing for clearance.
