Best upgrade for 3rd gen lower ball joint

My truck is right around 295,000 miles. It's getting to be the time I need to do some of the deeper maintenance on it, including timing belt and some other odds and ends.

I've done a couple thousand miles of fairly serious 4x4 between east Zion and Moab this year, and during the course of that tore the boot on a couple CV axles up front (and then gave this truck a mudbath in all the recent flooding). I likely need need to refresh other stuff in the suspension as well.

I'm thinking it'd be an opportune time to update the LBJ and other front suspension components. I'm currently running Bilstein 5100's and have been fairly happy with them. But I don't know when the LBJ's last got updated. Thus, questions:

- I'd hard the Taco LBJ's are an update, but replacement walk-throughs seem to indicate they're the same part.

- Taco tie-rod ends are mentioned as an upgrade, but... has anyone here bent / broken a tie rod before other stuff failed? I'm kinda dubious as to the utility of this upgrade.

- Is there an aftermarket provider that has a better LBJ solution?

- While I'm there, what other components would likely merit an update?

The use case is moderate-speed over fairly rocky roads (think the last couple miles of Hole-in-the-Rock, or the Orderville trailhead Jeep road, or the rockier parts of Moab) where there's a lot of vertical articulation while under acceleration. I am hard on this rig.

Any suggestions for LBJ (which seems to be the failure point up front) would be welcome along with other things that merit checking out.

No one has proven that tacoma/tundra/sequoia lower ball joints are any better than 4Runner lower ball joints. Tacoma LBJ's will require you to use Tacoma outer tie rod ends which will decrease your max steering angle and increase your turning radius. You can try uniball converted lower ball joints: Toyota Tacoma Lower Uniball LBJ Conversion - Anonymous Fabrication LBJ Uniball? I am personally not a fan of them but there are obviously people that are.

If you decide to stick with a normal lower ball joint then go with OEM for a 4Runner with new lower ball joint bolts.
 
Agreed with the above. There's a thread floating around on here about a company that makes these high speed, low drag type of LBJ's, I just can't remember the name. If I come across it I will try to post it here for you. I think they're a greasable type joint but I haven't read or heard much about them and their performance. For me, when it comes to lower ball joints on our trucks I would prefer to stick with OEM only, as I think most other owner's may likely agree. I have no clue about tie rod end upgrades from Tacos though.

It's settled then, OEM is still the best route to go - no issues with mine in past and I give them a pretty hard off road test - they just work. I'm about to replace mine for the 3rd time at 340K not because they show wear, just over 100K on this set.

Why not just measure the ball joint play to see if they are still .5mm and below. :)

OEM is the best that is all if you're running stock everything. not unless you change the whole LBJ assembly with custom fab suspension kit setup.

Mostly because the trans went out (340k) and it needed many bushings, original springs/shocks, so decided to replace all that (99 springs) so all would be 'new' from one mileage point forward, want toyo parts, many on back order, 2 more months for trans, makes me think of a 5 speed swap, hmm...

All very good reasons. :)

Ive had my Newer OEM lbjs on for 15k miles, but there has been a lot of off roading and hard driving in that 15k and im getting a terrible squeak with my rig basically existing. I read another thread and saw this

3rd Gen 4Runner Lower Ball Joint Imminent Failure Squeak - YouTube

Literally the sound mine is making so i guess my LBJs went bad after 15k miles? I jacked up the wheels and there was no play in them.
Do you have any input?

The max allowable play is 0.5 mm which is almost impossible to detect by feel. The service procedure for checking them is a little involved. There's a youtube video on the service procedure to check for play: https://www.toyota-4runner.org/2351611-post30.html Some people have also had dry ball joints and were able to regrease with a needle grease gun.
