after replacing my OEM shocks with monroe adventure and changing the front ball joints, i have noticed a slight differance to the truck looks, not driving.
steering is light and i dont have to apply any sort of excesive pressure, but i think the mechanin has made some mistake and the height is wrong???
here are some pictures.
front and rear wheels to arches distance to compare. (the tyres i use are 255/70/16)

Hi do you have the workshop manual? Its in it under ride adjustment in the frt axle section.

If not the measurment (worked by someone on here) was from centre of hubcap/wheel to edge of wheel arch is 20 inches exactly.
you need to adjust it from under neath at the torsion bar adjusting bolt and dont forget to realease the lock nut to turn the bolt for the adjustment.

Best of luck

my measurement was 48cm front and 52,5 cm rear (20 inches is 50,8 cm) so i am too low then.
but the bump stops have a low of clearance between the chassis, at least 5 cm on idle.
also a picture of the exact bolt would be nice

thanks for the help so far olan and looks but my english are not that mechanican oriented so i had no idea what the torsion bar was.
i think i have found it whatsoever.
do i have to tighten it or untighten it to get the 20inches from wheel hug to arches?? thanks again

Yeah thats it( in 1st picture) -release the top nut( of the 2 on the top of the Bolt) and then tighten away up till you get the right height.You will need to hold the second top nut for tightening/rising the pick up. you have 2.8 cms to go.I usually rise it up in stages and in between move the pick back and forth so there is no pulling laterly on the frt wheel distorting your measurements.nb* do both sides at the same time it easier.
you need to do it in stages and both sides.

and your welcome for the help.

luckily i got my hands into a second truck jack(my equipment is pretty amateur sadly and my car jack wasnt lifting high enough) and i will do this with first morning light.
doesnt sound like much more than tighting a bolt after jacking the truck and have some patience for both side to be equal, i will report tomorrow.
thanks again and sorry for covering the subject again but as said earlier my english arent that good to recognize each part.

ok so after i jacked up the truck and tighten the torsion bar (it was only half way and very very tight ) and after up and down the truck had 50,8cm from centre wheel hub to bottom arch (where it starts) huppily i went for a drive (was a lot easier to turn the steering) but when i parked and remeasured before i store my tools it was back down to 49,5cm. sound i keep tighting the bolt? it still has a lot turns to give its just past mid way but was it normal?? should it drop again??

:dj1 finally got it to sit at 50,8 exactly after a lot of trial and error but i did it in he end. trucks looks a lot better than yesterday and drives better.
last question, right torsion bar gave me the height i needed with 1cm of turns remaining, while the left one almost hit the end. i think it would be normal if my shocks were old but i replaced at summer with monroe?? :eyeroll

It would be possible for the torsion bars to wear or sag at different rates. The position of the adjusting bolts is immaterial as long as the truck sits level.

The new shock absorbers should have little or no effect on ride height, it is the springs or torsion bars that carry the weight.

Your truck looks nice and clean underneath, no where near the same kind of corrosion we see in the UK. :awesomework

my old terrano was the same. one side needed far more adjustment than the other. if it winds to the stop and you still dont have the height, then it might just be past its useable life.

well it was no huge differance just 1cm of bolt. i didnt see any marks on the bar and all the teeth were solid, maybe i have to reindex it next time i have to adjust it (hopefully in another 12 years :D )

yes luckily the garage helps a lot and everything is like factory new down. weather is like 90% sunshine, last time we saw snow was maybe 2008 :bow even the white spots you see are simple soil and water mixture.
well the height stayed there didnt lose after a mm after todays use, after work we harvested the vineyard grapes, truck is full of the juice(before it turns to wine at November start) so i will wash it tomorrow and get some more picks of the stance as well. differance was a lot noticable both visual and driving wise.

sorry for the late response but i think it was succesfull. much nicer overall. i think the mechanic definately has used smaller ball joints or something i have no other explanation for this.
next step is bigger tyres in next year, atm i use 255/70r16 like the ones it had from factory, i will fit 265/70r16 like manual says i can safely for a better look.
thanks for the help again!
this is from saturday my brothers wedding i told him we should use the nav, he wanted to take my civic :screwy

And you still call him your brother! :lol: seriously though I don't think going from 255 to 265 will look that much different but that's just my opinion, I would go for a different wheel to give it a better stance but not wheel spacers, I think it would look just like a pickup with wheel spacers fitted if you do, just something with a slightly different off set.

yeap sadly a bit bigger tyre wont make much differance its only minor but why not, its users manual recommended anyway.
but i know what you mean mate, i might be forced to get new wheels anyway when i fit my free wheel hubs (unless i can use the OEM nissan cap again, if the hub doesnt extend that much) cause i dont like the wheels not to look the same, rear with caps and front with FWH
 
#19 ·
I know what you mean about looking the same, that's why I have the metal caps on the back to almost match my FWHs, I assume you mean automatic FWHs? Because it will be a pain removing them each time you need to use them, that of course is also assuming that you use 4x4 a lot. I have just looked at my FWHs and it will be a tight fit for the original Nissan caps to fit, unfortunately I have just got rid of my original ones so I cannot even check for you! :dunno
Good luck with it though :thumbright:

hey Manikiatis nice "how to" just 1 question mate, when you leveled the truck at 20' from wheel arch to centre hub did both of your lower wishbones had the same angle? my drivers side seems to be a little flat but it gave me the height i wanted anyway
