sagging LN130

[s-dawson]

hi in need of a little help!!!!
i have a surf LN130 and the rear end is sagging.
i have searched the forum and cant find the info.
i am thinking of putting rear springs from a landcruiser as some of you have done. How much extra lift will this put over a surf with standard new springs ??
or if i put on new springs with a two inch lift will this just lift the back of mine by 2" or will it lift mine back to new plus another 2"
hope someone can assist.

New spirngs will lift it up to stock level maybe plus a bit, 2" lift springs go passed stock level by 2", LC springs do the same but i beleive the steel grade is higher.

LC springs and pro-comp +2 shocks will do you and cost about £150.

Easiest and cheapest way out is to fit the 20% uprated springs from Milners. Did this myself a couple of years ago. They lift the back end back to standard ride height and are much firmer. I did it myself in a couple of hours with just a Halfords trolley jack, a pair of axle stands and a socket set. The springs, if I remember rightly were only around £60 for the pair. 2yrs on and there is no sag at the back despite being constantly loaded with gear I need for work. I did post on exactly how I did it. If you do a search the post is still there.

Just in case you can't find the post - here it is:

You need a pair of good axle stands and preferably a 2ton trolley jack (got mine 18mths ago from Halfords for £27 the lot) but can be done with the standard Surf jack - just takes a bit longer. You might need some sturdy blocks to put under the stands as the Surf needs to be quite high to get the axle low enough to drop the springs out without having to use spring compressors. Put the axle stands just ahead of the brackets on the chassis that take the axle tie rods for safety Once on the axle stands you will need the jack under the diff to support then lower/raise the back axle.
Once on the stands take the rear wheels off as it is much easier to get the springs out from the wheel arch side.
Undo the two roll bar link rods from the chassis - don't need to take the bar out, just undo the two rods and let them hang - best with two open end spanners.
Undo the shock absorber mounts, at the bottom only as you only need to move them clear and to allow the panhard rod fixing bolt to be removed.
Slacken off the panhard rod at the axle mounting (the rod that goes across the back of the axle) to allow a bit of movement and undo the end that bolts to the chassis and take the bolt out. The rod should then pull out of the chassis mount and just hang down.
Undo the bolts/clips that hold the brake pipe that runs along the back of the axle and the one on top of the diff that holds the tee-joint to the flexible brake pipe from the body. Make sure that the pipe is free to move - it just removes the risk of stretching the flexible pipe and allows the axle to be lowered a little more so spring compressors aren't needed.
Use the jack to gently lower the axle checking that the brake pipe is free to move and not snagged.
To get the springs out I found that the easiest way was to use a piece of wood about 4ft long that you can slide between the spring coils and rest on top of the brake drum to push the axle down just enough to allow the springs to drop out. There should be no danger of the springs flying out as they are now not under compression. There are rubber cushions at the top and bottom of each spring that will need to be re-fitted with the new springs. It is obvious how they fit as the springs are different at each end.
It is actually easier to fit the Milners springs in than to take the originals out as they are actually shorter than the original ones. They lift the back end of the truck back up by being much stiffer and not compressing so much under load.
Once the springs are in place use the jack to raise the axle back up and re-fit the panhard rod at the chassis end first then re-tighten the axle end.
Re-attach the bottom of the shock absorbers and re-fit the brake pipe bolts and clips. Finally re-fit the roll bar links, wheels and - job done.
It sounds a lot but it really did only take me an hour on my own and I'm no great expert.
The result with the new springs fitted is well worth the effort - Surf does not now roll on bends, handles much better and tows my wifes double horse box without dragging it's a**e along the floor.

Just had mine done a week ago with some LA super trux coils, ride is much nicer and truck looks better

Land cruiser springs will also need a adjustment to the panhard rod (either a drop bracket or a adjustable one) and extended brake line

thanks for the replies i have decided to go for the landcruiser with the additional mods
