? about tacoma lean

You are right. 50 lbs out of 4000 lbs is about 1.25 %. Is not the weight but where is located what is important. You and your girl are located right in the middle of the truck I bet you that, when you hit a deep or a hole at 20 mph (off road), that 50 lbs becomes like 500 lbs. Take a look at all the Baha trucks and you will see that they are trying to strip off the front everything they can.

Off road, the front take most of the abuse. The front is not near as strong as the straight axle and flat springs you have in the back.

We (you, me) may not see a big difference when we make a small change but theoreticaly the suspenssion is afected one way or another.

 

I'm confused, how does hitting a hole at 20mph make a battery that weighs 01.25% translate into 500lbs or 12.5% of the vehicle weight?

And who the hell is driving 20mph off roading! I would kill my self and the truck, unless you are talking about high speed dirt roads...

I feel like I'm in math class trying to figure out the speed of a train based off the time it left and arrived minus the wind and gravity variable

 

I am pretty sure that the guys, down south, are going much, much faster then 20 mph on fire roads (desert racing).

When I was talking about % I was reffering to the amount of pressure that 50 lbs can put on that left spring when it hits a bump. I am not saying that 500 lbs is the exact pressure.
That 50 lbs can put as much as 10.000 lbs of pressure on that spring if you send it at the right speed.

The same way your truck would bottom out when you hit a deep on the highway.

I don't know the exact formula, but I know that any object moving at a certain speed will increase the pressure it excerse by a % at point of impact.
A better example would be ,,,

-try to walk on a soft ground and look at the print you left.
- now run and make a jump on the same soft ground. You will see that your foot print is much deeper. The deeper print is not because you you just put another 100 lbs in your back. The pressure and the mark you leave will increase as your speed increase.

I hope this answer you ???? and if not,, then I may have to go back to school.

 

My brain hurts.

 

Ok now take that equation and use it to tell me how much the front end absorbs with and with out the battery in it.

Yes you may be reducing the amount stress the front end handles by removing the battery, but only marginally when compared to the overall weight of the trucks front end and any variable factor such as: equipment, passengers, fuel, fluid reservoirs levels, tire pressure ect. will could also increase/decrease the amount of stress as well.

My point is not to pop your bubble, but to bring everything into perspective. It would stand to reason that if the battery only weighs 01.25% of the trucks total weight w/o passengers than by moving that load elsewhere, you are only reducing the amount of the force on the front end by 01.25% no matter how fast the truck hits the pot hole.

So to say that moving the battery out of the engine bay reduces the stress on the front end when you hit a pot hole at 20mph is true, but it only reduces the amount of stress by it's total weight factor of 01.25%.

When dealing with weight equations and load distribution, you have to keep the weight of the truck in mind as well.

 

Sorry dude, not trying to be a downer but I'm trying to explain that it doesn't make sense to me in an intellectual way.

You used an equation, and I'm trying to use the same thing to represent my how it doesn't add up.

I'm almost a college grad so I have been taught to read things critically, and verify. I didn't mean to be rude, but have a discussion about the subject at hand.

 

Everything you say,, makes sense and I get it. You are looking at the big picture. If you do the calculations in theory you make sense but ,sometime, as we all know, the theory (sometime) collides with the practice.
You don't take in consideration weight distribution. You are telling us (and this based on your theory ) that even if you have all the weight on top of the front suspension ????, the front should not be affected. The car is a mass and regardless how you distribute the weight on top of the four springs ???? it should behave the same.
If you ask any guy that race in the Desert- where would you like to have the battery mounted ????.

You would not be surprise if 99% will tell you that - they want that weight off the front suspension.

I been riding bikes for the last 20 + years and the same rules apply to them also. If you can have a perfect balance 50/50 front to rear is great.

Any weight you can remove off the front suspension and relocate more to the center of the truck- will translate in less dive when you brake and a better control in every day drive.

I hope we did not confuse the guy more then he was before. The guys that did it will argue that - is wort it. The other guys will tell you that- is not.
The best way to find out is to -go ahead and try it. It will cost you $25 in wire and 1/2 hour work. Take some measurements of the left and right (back and front) side prior you do this. At least you will have something to prove that the geometry changed a little.

This post was very constructive for me and I hope that , you, Masada, will turn out to be a very good Engineer. Thank you.

 

Believe it or not dude, my degree is in Justice studies lol.

I just remember some of my business calc I had to take.

I get your point when we talk extremes, removing everything you can off the front suspension (and just lightening the truck up in general) is going to put less stress on it. I just think it would take more than the battery to show significant gains, but every step towards that direction is a good step right. For me, it's not worth it for the simple fact that I don't go fast or dirt roads but crawl over stuff in 4 low and locked. I think someone with a Prerunner who races in the desert would benefit more from this modification.

However the question is still on the table for me at least, does moving 50lbs from the driver side really compensate for "taco lean?"

I have no theory on this one lol so no arguments from me that it doesn't. Again, it's not noticeable enough for me to try this mod.

 

My drivers side sits an inch lower at the rear end with a full tank of gas. I'm gonna try swapping the leaf springs around one of these days. wish OME would have taken the weight difference into account when they made springs for the 2nd gens.

 

yeah i dont see how anywho would notive 50lbs diff in a pickup truck
