Howzit,
I hope you can assist.
I have recently had a 50mm body lift done on my 2007 4L Hilux Double Cab added new HDL Safari shocks and spaced the coils. The tyres are 32 x 11.5 x 15.
My problem is that after the body lift the bakkie went the same as before, BUT after I have been in 4x4, it feels like the bakkie is “dragging”, almost like driving with brakes on and the fuel consumption has gone through the roof (and on the 4L this aint good at all)
After first stint in Mozambique the left inner CV boot tore, had this repaired and tested again, but bakkie is still not going as it used to.
Any ideas to the reasoning?
I have had all kinds of expert options:
Transfer box not releasing from 4x4, but I checked the propshaft and it has released
CV arms are too short and are pulling out after 4x4 activated.
I would appreciate any input at all.
Cheers
Martyn

Re: Hilux not going well after body lift
hi peter
I had the same problem I adjusted my load bin sensor on my diff when I raised my body by 100mm it seemed like my brakes was not releasing but after adjusting it it felt much better I hope this will help you I hope you come right with the price of petrol and diesel you don't want less km out of your bakkie

Re: Hilux not going well after body lift
Even with my std 75mm lift, i don't have that problem, put it on 4 axle stands and check if everything is turning freely

Re: Hilux not going well after body lift
If what Johan and Ernst is saying is true... it should be quite easy to pick up by just feeling the temp of the rim after driving a few kilometers.
I'm not sure how the newer models work, but know of someone with an IFS, where someone worked on the free wheeling hub and didn't assembly it correctly. This caused the driveshaft to always be engaged even though you "unlock" it. When they realised the problem and had it fixed, the difference in performance was very noticeable.
I told you that story so you know where I'm coming from with the next statement. Is it not maybe a case of an actuator or something in the electronic free-wheeling hubs that did not disengage caused the additional strain in the drive train and more drag?

Re: Hilux not going well after body lift
I Had a similar problem with my truck a few years back, no power heavy on fuel, it turned out that it was the water trap by the air-intake that melted away at the bottom, so have a look if thats not happened to your truck,

Re: Hilux not going well after body lift
Body lift should not let the CV pull out, except if the front was also lifted, i.e spacers, The angle of the sideshafts is too much. Same for the load sensor, it is mounted on the chassis and wont be affected by just a body lift. Also sounds if your front Actuator is stuck. Remove it and test in the open to see if the fork move.
For every mm lift in suspension the load sensor should be adjusted with the mm lift. As for the transfer case, check the front Actuator.

Re: Hilux not going well after body lift
The load sensor works when you load. So,the lower the loadbin goes, the more it will brake on the rear.
Lifting will mean less braking power on the rear, not more. So it cant be that the rear brakes are engaged while driving.

Re: Hilux not going well after body lift
The load sensor is mounted on the chassis and is connected to the rear axle. So a body lift only will not change that geometry. Only once the geometry of the rear axle versus the chassis change do one need to adjust the load sensorKaaskrul wrote:The load sensor works when you load.

Yes, its a conspiracy

Although it's highly unlikely it's the source of the problem as mentioned by the other members...

Actually called an LSPV .... (Load Sensor Proportioning Valve).

Re: Hilux not going well after body lift
Yes I know. But like I said , even if you lift chassis, it will mean less braking power,on rear wheels, IF you dont re adjust it. So if whoever did not adjust it, it cant be the fault for the bakkie not going well anymore, cause it cant keep brakes onto the rear wheels while you are driving, and holding the vehicle back, it cant beCasKru wrote:The load sensor is mounted on the chassis and is connected to the rear axle.

As you say, the rear axle has to move closer to the chassis in order to apply more brake force on the rear brakes

Transfer box not releasing from 4x4, but I checked the propshaft and it has released
CV arms are too short and are pulling out after 4x4 activated.
I would appreciate any input at all.

Must be the increase in aerodynamic drag........and we all know how the 4L struggles to begin with!
