Some lubes are better than others, which will be up to you; you will be the one that feels the friction when the axle is inserted.

First the receptacle box as to have which I prefer .5 gap. If it’s any tighter, the heat from the axle can cause the balls to tighten up on your axle and not spin freely. So pick the right box if you’re not using your own. Look around at the track there are different shapes and sizes receptacle boxes. Also, make sure it is a new axle you are installing or you would be wasting your time and can be harmful to you or others. To make this easier if you’re at a race changing this part and you’re running out of time, have a friend or a racer sitting next to you to help you out, it might not be the right receptacle box you like to use but it will work for a qualifier. First take some calipers and measure the girth of the shaft of the axle to make sure it is the right part you’re inserting, measure in three places, the tip, the middle and the closest to the connecting end to your body shaft. Do not measure the thread tip side that will be smaller because this is where you screw your nuts on the wheels. If this is the correct part then have someone just to be safe hold your box, have the person holding your receptacle box firmly when inserting the axle. Remember, you need to relax while the person helping you will be inserting the axle shaft. Remember relax or this can hurt your receptacle box and cause the axle shaft to bind while inserting. You might need a third party to help if this happens. Don’t forget the lube, there is a very good lube on the market called BANANA lube, it has been around for years and works extremely well. It will help insert the axle and will cause less friction than other lube on the market, be careful with this lube because it is high grade pharmasuiticle oil and the person helping you might not realize the axle shaft is not in right away and he might push too hard and that is where you might move and cause the damage.
