I think caster might be similar to rake angle in a motorcycle. That helps me understand the concept better.
its precisely the same
@@imakedookie Yes, exactly👍👍
I was thinking exactly same thing, like a big ole stretched chopper
Thank you
exactly… it is Rake
as opposed to Trail
I remember changing the struts out on a Toyota and forgot to mark them before removing. Alignment was so far out, the guy at the alignment shop wasnt too happy about that 🤣 Gave him more work I guess.
PS- loved the Bicycle analogy, great way to explain that positive caster 👍
Your the main man when it comes to informative automotive information. keep up the great work 💪
Explaining caster...hmmm, does that mean you're a telecaster?
Nice garage👀Doesn't have liquor cabinet though😪
For some reason, American autos used negative caster way back. I noticed this in the 60's because the front wheels would look like they are laying down towards the outside when turning. I noticed the difference when I saw German cars turn.
Bicycle example was a great explanation!
What caster angle works best for strippers? 😲
Great, but your video need to be explained in graphical show, it is normal methodology for any geometry.
Hola from Mazatlán for now! Shopping carts good example too
The highlight of the channel is the very detailed and informative explanations! I've been a long time subscriber!
I know Chinese, and it still made no sense. Nah, great video and explanation
Keep loading don’t stop 🛑 don’t kill the Chanel brother … you’re one of the fist Mecanic Chanel I watch …5 years ago love to see you keep the good job 👏
I REALLY appreciate your explaining this. I had heard the term, but never really understood it. Thank you!
So on a macpherson strut setup, the top pivot point would be at the strut mount right?
My man
My imaginary has limits🤣
But all the love
Probably wouldn't hurt to apply some castor oil on the steering linkage when you're done
Great idea to show engine stand casters I can never remember The difference between camber and caster but now caster on an engine stand or shopping cart is way simpler to remember.
How can I add positive caster to a vehicle that isn’t adjustable? I’ve got an F450 and it has almost 0° caster
Thanks 👍

From Nick Ayivor from London England UK 🇬🇧
Why bother to have positive castor for the front steered wheels? To increase camber angle with increase of steering angle to aid cornering performance, as well as provide self centering steering via literally jacking up the front end of the vehicle as the steering is turned.
my toyota verso uk says is not adjustable but u can dobthat by moving strut mounts as they have space left where bolts goes through the body
Thank you R&W for this informative upload. Your knowledge and experience is very much appreciated. Keep informing the people...
The bicycle example really helped. Thank you!
Sir I have a question, I have a honda accord ex 2010 , that I replaced strusts ,frt toes ,upper & lower arms , now it has caster angle weel issue to the front . How can I fix caster from the button of the wheels? Bc 2 alignment shops didn't fix my car issue
Out of all cars in the world you had to present 4ws prelude. It would be awesome if you were showing rear caster :) cheers
Good video, the bicycle analogy really brought it home for me. Thank you.
Do cars with mismatched caster angles drive straight? From this video I can’t see why they wouldn’t.
Question on my driver side front. The caster is 0.7 on my passenger side 0.6 is this bad?
Amazing!
This rebuild seems to be growing in complexity.
i noticed on my front wheels they are both positive but the driver side has more positive caster than the passenger. it's slanted more towards the steering wheel. also I have a question about the rear wheels. How can I center my rear wheels in the wheel wells. I noticed my rear tires are not centered like most cars and some models just like mine. they are shifted off center towards the front of the car so the gap between the tire and fender is almost half what it is at the back. I want to put a larger tire but cant bcuz it hits the fender on the rear door side.
Good video.
Learned a lot.
How is the insulation working for you in the winter now?
Lol San Diego doesn't have much of a "Winter" 🤣 Sure it helps a little bit. Surprised he didn't do a thicker insulation though, I guess he could add fiberglass later
Does negative caster contribute to death wobble? 🙏
Very good clear explanation of the set up and the theory. Thanks.
This is why a bicycle has positive on the front forks. Correct? Same with motorcycles.
Edit: I like your videos btw. Ty
So very very well explained
I was told my caster was bent? Is that even possible?? If so, what can i do to fix it? An alignment? Thnx
the UNMENTIONABLE?!!...
smh really? Avoiding this rabbit hole 🐇 🕳 I've gotten good at.
Very well done! Thank you!
I remember in my young days when I borrowed a bike, its very hard to steer and my toe is always touching the front tire. Now I understand that negative caster will give load on steering system.
Great video. The Caster on my 2021 RAV4 is out. It measures 3.8 and should be between 4.2-5.7. Is this considered out by a little or alot?
What is likely damaged? Strut? Control arm? Other? How would a mechanic go about figuring out what is causing the caster to be out?
Personally, I think the best example is a shopping cart simply looked on at the front wheels of a shopping cart, and the angle is abundantly clear
I just had my 4runner lifted and new wheels/ tires. Had an alignment and camber adjusted but it’s still a TAD negative and by a tad it’s almost unnoticeable. But being that it’s not exactly 0° is that an issue at all?
also, it’s important to understand why it’s so easy to go out of control, backing up at high-speed because your caster angle is in reverse
Looks like that Honda took more of a front end hit than my
04 corolla . The steering fights a little bit at highway speed .
I guess that is a symptom of not enough positive caster
I’m building a off road go kart , what angle caster should I use. Please help. I don’t want to much or to little.
4:34 "OK let's get the baldest tire in the shop on this thing..." lol, hey, nice informative video. Thanks for the explanation.
Keep it up man! I want to see you recommend some used vehicles again adjusting to inflation 😂
Great job of explaining in layman's terms!
That shopping cart example...Thanks!
Thanks. Excellent video and explanation!
Excellent video and information. Thank you for sharing 🙏👍
What if I have all new front end but the caster is still off
Trantow Garden
Thanks dude, I didn’t know this.
one of the best descriptions out there. Thanks
What??????
Thanks bro keep it up
Very helpful, thank you.
Very good information
You are amazing !
☝👍
Excellent Video !!!!!
Thanks 👍
W italians
i wonder why car manufactures don't do negative caster for the back wheels?
Would be a good idea if your rear axle steers in the opposite direction of your front axle, but terrible if they're steered in the same direction. Wheels that increase positive camber with increase of steering angle are not conducive to cornering well.
@@4G12 thank you for the enlightenment
keep them coming 👍
Awsome.
Great content
👍
🔥👍🏽
There isn’t any such thing as "self aligning torque". Why was negative castor popular from the 50's and earlier? Why does the steering wheel come back on it's own? There is only one spec for front end alignment. What is it?
There is no caster on front or all wheel drive cars,CLICKBAIT!!
2nd bishes!
Thank-you for what you do.
