MN Triton Front Upper Control Arm Bump Stops

MN Triton Front Upper Control Arm Bump Stops

Postby GregPaterson1995 on Tue May 17, 2016 9:52 pm

Hey guys

Im new to the forum and would like to get some advice on suspension.
I have recently lifted my 14 mn triton with a 2 inch lift kit and have come across a potentional hazard. I have found that the upper control arm/wishbone bump stops have minimal clearance. Just want to see if anyone else has had this problem when lifting by 2 inchs or if this is not a problem

Cheers
Greg

MN are 540mm from the factory (centre rim to bottom of flare) 575mm is about the limit you can lift them and still have good suspension travel so really a 1" lift (ML where 520 so 575 would be a 2" lift)

More than likely you have "lifted" a little too far. CV angles become a problem.

I have ordered new heavy duty control arms and extended ball joints to help with bump stops and cv angle

The suspension is brand new is it likely to sag a bit to combat this?

Yes it may sag a little.

Ball joint spacers do nothing for CV angles and can make wheel alignments difficult or not possible.

"new heavy duty control arms " The arms from Karrman offroad? For a little bit more may as well get the whole kit.

I bought the road safe extended ball joints not spacers, they will give approx 25mm extra between control arms, would these still have issues with alignment?

Hey Greg,
I have been looking at the extended ball joints aswell. How are they going have you had any issues?

So the ML's you can fit a 2" lift and still have some down travel?

If it is currently 520 mm then yes you can lift 50mm to 570mm and still have some down travel.

Rather than ask questions I often go and look at my Triton.

I climbed under and had a good look at my droop stops.

Using a jack under the chassis rail. I jacked up Triton till centre rim to flare measurement increased 50mm. I placed chassis stands under chassis. Then carefully had a look at droop stops.

I have adjustable struts. Mine are set to 560mm.

Exactly. The term "2 inch lift" means diddly squat. This is because it all depends on where you start from.

If your suspension is sagged and you're at 520mm then a set of raised coils may take you to 570mm. If, however, you have a newer MN with the longer factory coils and you're already at 570mm then the same new coils won't do anything at all.

In general, 585-590mm is about the comfortable limit to retain adequate droop. You can go higher, but there are implications.

suspension headache

Postby ShayeWA on Thu Apr 13, 2017 3:56 pm

Gday Fellas,

Been a while since posting but have a query regarding a suspension kit I purchased online.

Grabbed a fulcrum supspension kit with bilstein front shocks and helper spring for the bulbar with efs rear leaf springs with a constant 350kg load (as I thought that would help out with the custom steel tray I have.)

http://www.ebay.com.au/itm/MITSUBISHI-T ... Sw44BYKrEK

First off the bloke who installed it for me had to remove the front bump stops as there was no room for downward travel once the kit was fitted. What effect would this have on the front shocks when I go over bumps? As I'm noticing when going over just your average normal speed bumps the front almost jars....and its almost like the wheels want to punch through the bottom of the car.

Had the suspension now for a good 6 months, would it of sagged enough now to replace the front bumps, say get a set that are half the normal height?

http://www.ebay.com.au/itm/SUPERPRO-Sho ... Sw8oFXyQ18

Another problem I have noticed was that when steering and trying to say turn into a carpark the steering kinda wants to over steer I guess would be the best way to describe it, Like there is no limit to turning??

The bloke seems to think that the over steering is due to a wheel alignment issue?

Are the front bump stops important? Say enough so that I need them back in ASAP

I'm currently at work so cant upload any pics etc of the setup I have but any feedback or trouble shooting would be great.

sounds like it's been stuffed up quite severely.
bump stops must stay in ! if they don't fit then it's far too high and your jarring is a direct result of this, not only is it uncomfortable, your shocks will be stuffed in no time at all, take a measurement from the very center of the wheel to the underside of the guard and let us know what it is, I'll guess
610 mm anyway it's well documented in other threads and and this one is likely to be merged

Merged. See the previous posts and do a Search on "bump stops" - lots of hits there.

As snakesoup suggests, post up your actual heights - measured from centre of wheel to underside of flare/guard. This will assist other members to understand where your suspension sits and what options may be available to you. Certainly, refitting bump stops will be a priority.

Bump stops are very important as they stop metal on metal contact of your control arms with other structural members.
The jarring you are feeling is your mobile metal low control arm belting into the metal fixed components.
You are risking damage to your front end if they dont go back in.
The shocks are not at risk here.
Something is very not right.
The upper bump stops, mounted on the lower control arm, should have reduced clearance but should have been able to be reinstalled at upgraded suspension fitment

OK Guys,

Thanks.

Home on Tuesday will measure and report back.

Say it has been lifted to high would I be looking at changing just the front shocks?

Or could I get away with the shortened bump stops that I posted the link too?

should add I only have an ARB whinch bar delux and a light bar up front.

You would either have to change the coils or add more weight, like a winch.
Front struts have no effect on height. They only limit the coils rebound
Sounds like your coils are incorrect, assuming the install was done correctly.

OK so if I get the coils changed re add the bump stops I should solve the problem.

Fingers crossed its a simple fix like that.

Thanks for the help. its going back next Friday to sort it out.

check out if they have preinstalled the collar which is the coil seat on the upper or lower setting.

the Blistien struts allow for 2 positions, and the "helper spring" bit to combat the bulbar suggests that they might have set it at the higher position.

If this is the case you will be able to reuse everything you already have, just need to relocate the bottom coil holder to the lower position, not something you can do at home, but cheaper than new stuff.

Spoke with Matt from fulcrum suspension where I got the kit from just to confirm it was with the heavy duty spring option.

So possibly not enough weight on the front?!

So hope it's what you have just suggested, or Matt seemed to think I could just change out the coils and get the standard ones at $200.

Wish I had of read up a bit more before I touched it :oops:

Roll back a few steps Shaye. From what you have described your ride shouldn't have left the workshop with the suspension in that state.

Is the 'bloke' actually qualified to work on suspension?

I'd be asking for a swap of the coils, if the first set were inappropriate.

Hopefully you get it sorted soon.

Mate,

Yeah I'm pretty disappointed it left the workshop as it was. He only installed it so had no say in the kit I ordered, as I ordered it rocled up and asked him to fit it, still no excuse I guess for handing it to me like it was.

I will take the blame for ordering the wrong coils but, so I guess that sits with me.

Just hope that it hasn't done any long term damage being the way it has been for a bit. Lucky in that 6 months prob only driven it for 3 and 90% of that on road.

OK

So had the neighbour go over and measure the height for me.

Pretty much 600mm all round (which I know isn't good)

Would the standard coils lower the front by say at least 10-20mm?

Tyres sitting at about 38 PSI

585 at the front is about spot on/as high as would be recommended back can be over 600 no probs usually
