why IFS?

Nah, the 4-wheel steering GM trucks had a solid rear axle, and it was available on other models besides the Denali.

 

It's because it's a ford

 

My mom's stock 2007 F250 has done that wobble a few times. Pretty scary when you're doing 70 on the freeway and loose all control of the steering.

 

sas will articulate much better than any ifs set-up.

toyota more than likely did this to make the truck more road friendly but, imo that also goes against their target market's wishes.

they should imo switch back to a solid axle design but, they should also offer the d4d diesel here as well but, this is never going to happen because they are retarded.

my father had an old toyota pick up that had a solid axle and his never wobbled once in over a 100k. i think its a ford thats why

 

I doubt you'd see much change over the current suspension setup.

1. IFS provides the best compromise between on road comfort and off road usability. Playing the 80/20 rule, 80% of vehicles are going to remain on road, or do light offroading.

2. The Tacoma is targeted towards young males and small (read: new, young) families. Small family = room and comfort, young males = toy vehicle. Young people can put up with a bit of discomfort from the rear and less accouterments if you make it feel sporty and cost less.

3. If Toyota is going to do IRS, it will be the Tundra. Tundra owners have money and are going to be more interested in comfort. I see the Tundra becoming the Escalade EXT competitor.

I doubt the FJC will see a solid axle, either. Despite any usage, It would look like a technological step back from a sales standpoint. if you look at Europe and Asia, they would lose interest in the vehicle - "what's this? Toyota got rid of modern technology and borrowed my suspension from a stagecoach?"

 

Wouldn't IRS effect the tow rating.. Leaf's can handle more weight than coils. IRS on a truck kind of diminishes the purpose of it being a truck.

 

Standard leafs can support more of a load than a standard coil. However, it wouldn't be that hard to design a coil that can support the same load as a leaf. My dad has a '64 Chevy half ton. Supporting its solid rear axle is a very large coil on both sides.

 

well played sir. Those things will break your spine though!

 

Yeah coils are definitely better for comfort. I was just saying that most light production trucks have leafs and a solid axle in the rear. They're definitely using the best of both worlds when it comes to an IFS on Tacoma's. When they're used on the road anyway.

Super Heavy Duty TRD SFA version would be a cool option though, but be willing to spring for a few more $$$

 

You can't deny that independent suspension give you a lot more ground clearance. and as the photos a few posts back demonstrate, when the wheels are articulating you can still have them flat on the services they are rolling over. I think that if money were no option and you had beefy enough parts, fully independent suspension would trump solid axles.

 

Oh Hell yes! I think Toyota of Australia produces a badass land cruiser truck with solid front axle.

 

The HMMWV's have a "gear box" in the spindle so the half shaft is connecting above the center of the wheel. That is how the get their height with halfshaft's. Also the HMMWV's also have thousands of pounds of armor bolted on to them as well. although this has caused problems with the suspension or so I am told.

 

Volvo portal axles?

 

take a poll idk if there would be many on this site that would turn down a factory solid axel on their tacoma.

for a real 4x4 it's silly imo not to have a solid axel under it.

 

I have work for a GM dealership and see EVERY new vehicle that comes in. I have NEVER seen any Denali model come in with a IRS. Yukon, and Sierra. I can PROMISE you that we will see it on the Escalade before the Denali. It has always been like that, and always will be.

 

First off. The 04-05 denalis did NOT have an IRS. The quadrasteer was an ABSOLUTE flop. Warranty issues where going out the door left and right. They where absolutely junk. I work for a GM dealership, and for the first 3 years of me working there, I can promise you that we had a qudrasteer system in there at all times getting repaired. Just like ther Hummer H3 now with there head issues. Also, talk to a Army mechanic that has worked on those Hummers. They are also ABSOLUTE junk. We are the only Hummer dealership up here in Alaska, and we can't get rid of the pieces of junk.
