Cv axle replacement

OEMs are the same length as most replacements. They are able to move through the whole range of suspension travel, so no need to replace simply because you are riding an inch or two higher than stock. The boots however will pull away at the clamps and possibly wear out sooner when lifted. Most will use a tighter clamp on the CV to prevent the boot from pulling away. Some (with more lift) will reboot with boots that allow for more angle than stock, like the Porsche 930 boot kits.

OEM axles are completely fine with a 1" lift. The closer you get to 3" of suspension lift, the more likely the boots will tear or you'll see odd joint wear, especially on a joint that's spent most of it's life at OEM height. The lift you're throwing on, especially with 4600s, still allows the shock and axle to cycle the same amount of distance as a stock truck. Your lift will move where you are resting in the shock's cycle, and will result in the CV joints resting at a slightly different angle than stock.

Thanks for the info. Good to know, I'll stick with OEM then, the place I was going to take it in was trying to encourage me to go aftermarket extended travel for around the same price--but I'd always must rather have oem if given a choice

See my thoughts below on the Trakmotive "extended travel" axles:

Once the c-clip is inside of the differential, it should not be able to come come out easily.

One thing about those Trakmotives is they have the sliding center shaft. Those might be useful for Toyotas that have Tripod joints on the inner CV, but since our OEM CVs are double offset on the inner, I don't think they should be compared. I do not have the exact numbers for our stock CVs or stock Toyota tripod CVs, but Tripod joints are limited to 23-ish degrees of articulation, and double offset or Rzeppa should be closer to 46-50.

The inner joint on the Trakmotives is fixed, vs the OEM inner joint being a a plunge joint. As the suspension moves the shaft on the Trakmotive plunges, rather than the inner joint on the CV. Additionally, the Trakmotive has 8 ball bearings vs 6 ball bearings on the OEM. 6 ball bearings from OEM likely provide less friction.

I'm curious how the sliding center shaft holds up to lots of torque, could potentially be a weak spot. I'd be curious if the standard Napa axles are tripod axles. If that's the case, the Trakmotive might provide a little better articulation, but for most people, especially DD's, I'd say those would be fine and just use the Napa warranty if a joint breaks.

My conclusion is the Trakmotives don't really provide much over OEM Tundra CVs, they're just constructed and operate slightly differently.

I would recommend just rebooting your OEM axles. I've done two of my own now and it is not bad at all, just a little messy. I'm going to try out the porsche boot mod on my spare axles that I'm about to reboot. My tip is to buy oem used axles off ebay and reboot them. I've bought them with a return policy and for $100 or less each.

Are you sure? I can't add to any carts via the parts network sale dealers. Like your screenshot says, unavailable!

Shit. You're right. My bad.

You have a good eye. My power steering reservoir cracked awhile back and leaked all over everything for a few weeks (kept filling it because it was a slow leak) until I could replace it. The upper / inner boot is not intact and grease is spewing out of it. This is new. I replaced the brake pads about 3 weeks ago and I didn’t notice all of the excess grease, outside of the power steering fluid.

If it's just loose and not torn, simply re-clamp it. It's typical for them to kick out grease after lifting, specifically, but if the issue is that the boot popped off the clamp site, re-clamp. The diameter is printed on the clamp (like this), and here's a list of NORMA clamps that are good for the job.

You may be looking at the discontinued parts, they dont seem to be linked to the current part number

When parts are fully discontinued, you can't even load them up at the national Toyota parts site. The fact they're still in the system there suggests they have limited availability at the moment.
