Was thinking of fitting low profile bump stops to IFS on Hilux to crib a little more travel from suspension.
Where can you get them in Australia and does anyone have any comments about doing this?

I'd be careful as the existing stops probably squash to half their height under load as it is, fitting thinner/lower ones might lead to metal contact.
Will fitting the lower ones increase CV joint angles past the safe maximum?

The reason the bump stop is there in the first place Twinkles is to avoid the shock absorber bottoming which could cause it to blow the foot valve out. Not familiar with how much safety margin there is on an IFS Lux but it can't be much & would be required to allow for the bump stop to compress to half it's thickness on big impacts.

As the Guys above have said ! I would also like to add that letting the C.V. shafts tilt at more extreme angles will make them chew out or fail a lot quicker than If they were left alone.

Agree with that one.
Most probably more CV joint wear, and as above, chance of wrecking the shocks if they are travelling beyond thier limit.

Up to you. If you want to jack it up to get more clearance, why not bigger tyres?

Hey, I own a pajero, I know what limited travel in the front is like, and have looked at doing the same to mine, but havn't.

I'm after better articulation really, not height. I need to wind it up a bit for the 31" muddies I have on my 2nd setof wheels. They rub the guards, but don't want to go to any extremes of raising it to put bigger tyres than this.

Twinkles,

Interesting set of replies. Like you buying the Lux, I most probably bought my pajero for a number of considerations, not just off road. So the off road limits are a compromise. As you have done, the lokka in the front is most probably the most effective fix for now.

Have seen an article in a mag where some one transplanted a solid axle hilux front suspension into a IFS Hilux for more articulation and traction off road. Serious work, serious money :o) Worse on the road.

So if you need a real good off road machine for the weekend, why not look at a Suziki Jimny or the older Sierra? Or a 2nd hand 80 series or same age patrol? Or older solid front axle Hilux? Might be cheaper in the end, and if it breaks, you still have your new Hilux for during the week.

Just been down this road for a hill climb car that is still street registered to stay in a particular class. How much race and how much street?

Hi Oldplodder. I only want one vehicle. I considered buying a vehicle with live axle in front, but came back to Hilux as is a good all round vehicle, comfy to do long trips in as well as reasonable off road. Just trying to improve off road capability.
I have read that article on replacing front to live axle. Too expensive!
When I purchased Lux it had bull bar, tub liner, tow bar, UHF radio and only 33000kg. I've put in a long range tank, 2.75" exhaust, snorkel, TJM canopy, TJM suspension (not tortion bars yet, still to decide about these), Lokka, locking hubs, and plan to fit a DPChip. Probably go duel battery at some time as well.
I have long service leave to take when I'm ready so planning for long trip.
I tow an off road hard floor camper.
My first 4wd was a Suzy Stockman. My daughter had a Vitara. I've had a 94 petrol Patrol and 3 diesel Hiluxes. So driven a few. I like having a ute.

Same thoughts here.
Mainly used for touring.
Now tow a CT sometimes.

Sounds liek you got a good Hilux.

Interesting going to Cape York with a group.

I had slightly more agressive AT tyres than the rest. The most agressive I could get without going to MT.
I was lifting front wheels on some of the OT creek crossings.
(One place some one reckoned I had one front wheel about a metre off the ground. They didnt get a photo :o( )
But I was the only one that got through all of it without a snatch or tow.
Almost didnt get through on a couple though.

Just took it careful and checked everything out as I went.
Bit of thought and a good line makes up for a lot.

I only have the standard rear LSD.

Found the same on a few trips.

Hi Oldplodder. When are you planning this trip to Cape York? I'd love to do that trip some time.

Thanks for the comments. My Lux is fitted with locking hubs so CV joints only rotating in 4wd, at slower speeds. Usually going slow over very rough terrain when requiring maximum articulation. The low profile bump stops I've seen on the net in US are made from polyurethane so may give a harder stop. I've also had a Lokka fitted to help overcome the limitations of the IFS.

Have you thought of removing the sway when offroading, as this would free up the action of each driveshaft, allowing each side to articulate up and down independant of the other, where with the sway bar attached when one moves up it tends to affect the other somewhat

just a thought

Have you removed the sway bar on yours. I have put the "comfort springs" from TJM on the back. I had firmer ones on my last Hilux, got better lift but not better articulation. The softer springs give a great ride on and off road, and seem to articulate better. They're not as good around bends on bitumen though.

Twinkles I did this a few years ago with a V6 4Runner. I just took the bump stops out and cut them in half horizontally (half thickness) then put them back. Yes you get a bit more travel (only a bit ) but the steering rods then come down further and bend the Idler arm on rough tracks. The rods push the Idler UP not side to side and bend it $180 each. Not worth doing for the small amount of travel you get. Try to get more travel from the rear wheels would be better

Thanks desray.
This info about the idler arm has convinced me not to do it. I had to have one replaced on my last Hilux, so consider them under enough strain already.

I cut my bump stops on my Rodeo and every so often I reckon this high pitched pop noise I heard were the shockers topping out.
At the end of the day, and after all the experimenting with the front end of my Rodeo, check with ARB to see what sort of height they say they can tweak it to and stick with that. The reason I say this is because they can't go modifying vehicles making them unreliable. All I did was make the front and of my Rodeo unreliable. I broke a cv and I also bent a tie rod. When I went to the 'CV joint' to buy a new cv the guy there informed me that they do so many Hilux cv's that they can't keep up and need to buy them from wreckers.
