Hey guys, CV axles and wheel hubs.

[jason ross]

I have a 2023 1500 Limited w/ 4" BDS lift and air delete. 2.5 FOX shocks and bds 3" coils in the rear.

my CV axles and wheel bearings are on the way out.

Can anyone suggest a hub assembly other than MOPAR?

note: So far i have looked at trackmotive extended travel CVs, granted they are for the DS however i have read people have fitted them as they are almost exact.
And i am aware of the larger hub assembly for 22" wheels. I do not use 22" and are moving to 18s as we speak. so maybe a smaller hub is suited.

Thanks in advance

If you had 22's originally, you have to stick with 22" wheel hubs. The knuckles are different, so unless you buy standard knuckles, you can not run the smaller wheel hubs.

ah ok good know, i think that must have been the large bore knuckles in the BDS kit.

Curious how many miles? How do you know they are going out?

50,000 miles.

I strapped a go pro to the lower control arm on each side, there is a lot of play in the CV axle where it meets the stub shaft, and the bearings are howling. Rotational vibration through the front of vehicle as well. I got under and looked and surely enough a ton of play in both CVs.

The cause of the issue was surprising. All my angles are dead straight, however what i noticed was at high speeds when driving over wavy roads the CV axles were moving outside of factory tolerances. I have a ton of tire droop on the rebound, that mixed with the high speed (80 speed limit, with 90 for over taking) looks to have worn down the CV axle, the bearings have followed. I first notice this when i had a brake line leak, even though i am using the extended BDS brake line. So i just have a lot of articulation for the standard axle. I am looking into extended axles.

Now when i mean driving on wavy roads i mean for 500 miles at a time. the total journey is 1500 miles 1 way i have done it at least 4 times there and back.

I'm curious when you say outside of factory specs? What are the specs?

Also you say a ton of droop, but the dropped differential and crossmember should keep everything factory aligned, unless you changed struts with something else giving more travel?

 

[jason ross]

The fox shocks have a ton of travel and the upper controls arms being in a slight increased angle rather than the usual decreased angle assist that.
The factory specs for maximum CV angles are from memory are around 23 degrees at both joints.

This would not be an issue at low speeds hitting a wavy road, however at a constant 85 miles - 95 miles p/h for 300-500 miles at a time is a different story.
The 4 points of pressure are both joints and both ends of the CV axles. Constantly hitting maximum angle has appeared to transfer that energy to the CV spline where it meets the stub shaft.

To put it simply if i jacked my vehicle up from the front cross member id never get the wheels off the ground. And i have a high lift jack. The travel is pretty impressive. I can measure it tomorrow.
As i said before the go pro caught the CVs from dead straight to full angle.

When i mean wavy, it is a sealed road that's been heavily affected by heat and rain, which makes its like driving a boat on a swell. if i didn't have this long travel suspension id be airborne. I just have no choice but to drive that route.

The fix would be higher angle CVs trackmotive do a 47 degree angle, its for the DS but they are almost identical.

Gotcha! Makes sense with the Fox suspension.

Dont get me wrong fox is great but i was not prepare for this my travel. haha

@boogielander Has the 3" BDS setup w/ Fox and does crazy driving, don't think he's had any issues

I don't have anything to offer, but I do have a question. How are you driving 80mph on such a rough surface? To get that much travel requires a very rough road, right, so 500 miles of that sounds dangerous to me. Just asking for understanding.

not bds.
fox 2.5 dsc all around,
700lb springs in the front, clayton 2.5" HD springs in the rear.
full carli components minus the brake line.

no issues.

i go 80mph on rough surface too lol but for sure not that often. even in a fully built full Thuren catalogue HD truck (the kind of build that eat Raptors and TRXs for breakfast, lunch, and dinner) it's sketchy to go that fast all the time without being caged. i have a internal limiter that slows myself down lol

that said, his 4" kit should not have full droop even on rough surface, unless he's catching air to fully droop the suspension. the only way I see it's possible is he only used the coilovers and did not use the diff drop bracket thing, but that would make sit at "droop" at ride height and therefore, make the geometry all kinds of incorrect.

 

[scottmoyer]

Going 500 miles at 80mph and getting "air" is exactly what I was thinking. So, with that, I was also assuming that if that was how the truck was being used, that it would be built better to handle that, and when replacement parts were needed, they would already be defined based on the use of the truck. This makes me think the OP is a professional driver but asking amateurs for advice on parts.
