Upper control arms are popular because they don't have as much load on them as a lower control arm. So it's easy for people to manufacture them and they technically fix alignment issues after lifting a truck. The downside is, to give you that caster it takes tire clearance from you. You can add more caster with the lower eccentrics sometimes but really you're just trying to make up lost ground. The better alternative is high caster lower control arms. They are more expensive , but they move the bottom of the tire forward instead of the top of the tire backwards to get you more caster. That gives you more tire clearance right off the bat while fixing alignment issues that happened after lifting a truck.
New 24 sr5 prem. 4R owner here. Just blew all my cash on the vehicle, but one day looking to do some of these adjustments down the road. If you aren't a teacher yet, you should become one man! Really informative and easy to follow. Thank you for describing it to me like the 5 year old I am!
this is fantastic! why have i not heard other overlanders talk about this?!
Awesome video and awesome timing. I'm waiting for a lift kit for my 4th gen to be delivered and am doing research on how to keep factory-like ride quality. This is the absolute best summary of the geometry that I've seen amywhere.
Great video. Very informative!
Thanks for great video im about to lift my 4runner.
Great vids man, love your maintenance stuff, please keep it up
Thank you!! 🙏🏼
Amazing video! Very well explained. These Toyotas with a 3in lift and stock UCA won’t even get 1 degree of caster with camber close to 0. Highly recommended the UCA anything more then a leveling kit
Thank you! 100% agree with ya
Great video and great explanation. Like the drawings . 😊 Thank you for the great info ! On the pan hard bar bracket kit . I did some research and if you lift the rear over 2in this is needed . I was told that if your lift is 2 or less then 2inchs it is not needed . I have a 2in lift in the rear and it drives like stock . I hope this helps anyone looking into that mod . Mine is a 2019 4 Runner.
Thanks so much! And thanks for sharing!
I just bought panhard kit after a year+ of having a lift
Where did you get your 4runner lifted and how much estimate and how many inches did you lift?
Great video. Very informative. I have a Limited with XREAS removed and Bilstein 5100s, Wildpeak ATW3. 1.5” lift in front. Stock UCA LCA. Even with caster pushed to the max 3.4 degrees I get some wandering on the freeway. It’s tiresome on long trips. Might need UCA to get more caster I guess?
If you have 3.4 degrees then it probably isn’t related to the caster. I would check for worn loose ball joints/bushings. I would jack the front end up and grab the different components with your hand and see if there is any movement. Try moving the wheel, rock it and twist it checking if the hub is worn or loose. Grab the tie rods and see if they have any play. You could also remove the skid and have someone turn the steering wheel back and forth while stationary as you look for movement or play. Place a pry bar under the front wheel with the wheel off the ground and see if you can pry it up. This will check for play in the LCA ball joint. Hope this helps
@@T4Rgaragewill do. Thank you.
@@wolfeadventures any results
I did a 2” lift. Was told much more and would have to do “extra stuff”. I’m assuming it would be the law changes. So agree should be good at 2”?
I have kings all around aftermarket UCA and medium duty springs. 3.5’ lift in front and 3’ in the rear. Even though I have never experienced any of this conditions do I still need to do some of these mods ? Or is this only necessary if you’ve experienced some of these issues described. Thanks.
To be honest, a lot of them you won’t notice until you make the switch. For example, as soon as I put the panhard correction on and hit a bump it was aha moment. I instantly realized a big difference and my alignment is better on be paper. It’s up to you really, the trailing arms probably aren’t necessary unless you go over 3” or experience vibrations from your pinion angle being off
What about only 1" of rear lift? Are Panhard correction and sway bar links needed?
With 1” I wouldn’t worry about it, you’re good 👍🏼
At what point is it important to make these corrections? Ice got a 1.75/1 inch lift on 5100s and eibach springs and so far it doesnt seem like its been affected, although i havent checked angles
Ah. Guess i should have finished the video first. Thanks for the info!!
What sway bar??? 😅
I figure the rear better be working if the front isn’t there haha!
Rear only!
