General Handling - continued from LSD spin out thread

[Sparks61]

I've put this in a different thread as this is off the topic a bit now.

I haven't had the chance to disconnect the rear ARB yet but other things have turned up.

Since my minor "off" a couple of weeks ago I noticed I had a squeak from the front right going over speed bumps etc. I had a quick look and saw the front ARB had shoved across a bit so I assumed the drop link was rubbing on the edge of the hole in the bottom arm. Took it to the dealer and they had a look and put their hands up to having fitted the ARB back upside-down last time :doh

When the foreman had a closer look he noticed the front bumps stops were MISSING and the rear bump stops were completely knacked - flattened and hard.

Sooo they refitted the front ARB and fitted new bump stops all round. Now whether I am paranoid or not I don't know but the handling seems MUCH better. I have noticed the front bump stops are very close to the stop plate and the rear one is WAY bigger than what was there and also therefore much closer to the stop plate on the axle.


Here is the front bump stops - not a great picture but you can see how small the gap is

Here is the rear bump stop - the old one was completely flattened (about 1/4 this height) and full of mud - effectively solid blocks.

So my thinking is the suspension is quite dependant on the bump stops in normal compression ranges. The front suspension will quickly be onto the stops and so this effectively stiffens the front and takes some load off the rear - a good thing. Also, without the front stops, the roll was taking the rear onto the rear stops which were effectively solid blocks ( not the highly compliant things now fitted) and this shock loaded the rear and made it break away.

Right or wrong I don't know :nenau but I still intend to release the rear ARB and see if it improves things more.

The front's wrong for sure I'd guess your torsion bars need adjusting up a lot. The front of the truck should be about 10mm lower than the back(or less) ish unladen.
The rear bump stops are infact spring assistors and help out when the truck's fully loaded up. So shouldn't be anywhere near contact in most cases.
Can you get a side on pic with truck on the level and one from the front underneath too :thumbs
We like pics :lol

There is a workshop on torsion springs I think, worked for me:clap

The place to look in the manual

I will go along with what Makeitfit says, regarding the front stops, I didn't know the rear ones were spring assisitors though.

Well Makeitfit - "Houston we seem to have a problem". Here is the pic - poor quality but it was getting dark (the pic doesn't show that). I have put on the dimensions I measured from the bottom edge of the plastic trim to the centre of the hub as best I could - probably +/- 2 or 3 m

Going to have a look at the manual and downloads tonight for adjusting the torque rods.

 

[makeitfit]

Ha I'm on a roll today
Yep that defo needs winding up some. There is a proper way of doing it in the downloads but it's a bit geeky :lol

Before i adjusted mine the hieghts were similar, it really was qquite interesting under hard acceleration, front end would rise a good 6 inch making it feel like it was going to do a wheelie

 

[Fez_uk]

Yep my front was doing similar thing, wound the torsion bars up.

 

[Sparks61]

So I've had a look at the manual in the downloads and it seems the torsion bars seem to be a case of fit them; adjust to the 77mm on the adjuster and check they are right. Assumption is, if they are not your bars are twisted. So - does everyone actually just wind up the adjusters some more and if so how far can you go ? Not doing it right away as it is a bit snowy right now ....

 

[makeitfit]

Phft, just wind it up some more mate, it'll get there in the end
