Fg Ute Axle Tramp

111 posts in this topic

I used to get it bad in my BF F6. Couldn't break traction without a violent series of axel tramp. That car had 19" witha lower profile tyre.

Since getting the FG ute I can honestly say I have never experienced it once. It breaks traction nicely and feels smooth even over bumpy roads. I have 18" with standard XR suspension. Oh- and it's a manual too.

One thing that really struck me about the ute vs. sedan was the amount of oversteer required in the ute to hang the arse end out. In the sedan I frequently had the back end ready to overtake the the front. With the ute I find it far more foregiving and very easy to control the slide (all on private roads of course!)

GLOO - something not right with your set up. 100% of the time? Do you have factory suspension/tyres? Do you carry a load all the time? What are your tyre pressures? I run mine at 40psi.

I got the 19" luxo pack wheels, car has 3000k's on the clock. So its brand new unmodded. It even tramps in the wet.

Its never towed and never had a load on it yet. Right out the factory its been a bitch. Its a manual also.

I might check tyre pressure tonight, I havent yet scince its brand new so maby there running soft.

Dunno what the deal is, ill get some good suspention when money alows. Im hoping that will help it.

never had a load in it?? whats the point of having a ute then?? try putting a couple of bags of sand in the back, bit of weight in it should solve the problem.

I didnt buy a ute to carry a ton of sh*t around, I cary sh*t in the back all the time, biggest shift was maby 120kgs, 5 20kg rapid set bags and a bunch of tools required for the day. Generaly just my day to day tools and enough room to put some small machinery in, flex drives, quick cuts, gennies + power tools. Not really real loads though. What are the utes rated at for load carrying? 800kgs? I might drop 20 bags in the back over the weekend and see if that gets things right.

Keeping bags of sand in the back permanantly doesnt justify doing skids and I try not to do skids with sh*t the back any ways. Ill find a way. Maby it needs a good 400kgs to get everything sitting right and set everything in right. Like I said its brand new, only a few weeks old.

Had some bilsteins fitted yesterday along with Lovells springs. Looks the goods, so hopefully it doesn't tramp it's ass off tomorrow night at the drags like usual!

I think I have had mine tramp twice since I owned it and both times were because it hit a bump as I nailed it

Its fairly easy to drive around it. Not sure about an auto though. Will only get it when nailing it and hitting bumps, just dont dump the clutch with more than 3500rpm, ie "launch control". Dont get it in the wet will just fish tail around.

A good fix is to pull the springs out and have them reset in the opposite direction. This means that the spring will be fitted flipped over and leaf eyes will now go above the front pivot and through the centre of the rear shackle, rather than from under the bottom. This reduces the leverage the car and spring has on the shackle assy's and increases their curvature making them less prone to go into a large "s" shape under load. See how they deflect when following a car from the lights.

Also fit poly bushes to the eyes and if possible the saddle mounts where the diff sits. This will tighten up the "loose points".

Fit good dampers as already suggested.

My old xD used to suffer from axle tramp if you were too aggressive on the clutch. I did all this about 15 years ago, and have not had it axle tramp once since then.....no matter how I treat the clutch now.

Axle tramp bars:

-the ones underneath tend to be grass catchers and actually deform the spring under load. Less than optimal.

-the ones above the spring that fix their other end to the body (like the old standard XC GXL and xD ones) have a different body pivot point than the front of the leaf spring and result in suspension bind at large deflections. Not so bad with sloppy rubber that was fitted to them. This bind CAN RESULT IN NON LINEAR SUSPENSION CHARACTERISTICS AT HIGH SUSPENSION DEFLECTION. Read erratically tail happy. Also less than optimal.

Also, springs that have been lowered by lessening their arch to bugger all will suffer more from tramp as it's easier for them to 'wind up" and then release over and over.

The critical leaf in the "stack" is the second longest one. The critical part of it is how far it is from the shackle eyes. This can have a major impact on the stiffness of the stack. The also have plastic pads between each of the main springs at each end so they don't squeak and slide smoothly.

Another solution is to get some of the upper shocks of the quad shock 80's Mustangs. These lie horizontal and would dampen any sudden return twisting moments (compression).

Adding weight to make it slower??????......... :auto: :ph34r:

The reset was done to my std Ford leaves.....no dramas in 15 years, so a reputable spring shop should be able to do it and re heat treat them.

So...

Have the factory springs reset, but up side down.

Fit poly bushes

Fit good dampers

Ill get onto to a suspention shop and see what happens.

I have an 09 manual, it's lowered an inch and has 20's, only seems to tramp if you are giving it the berries and you grab second and hit some bumps when breaking traction... only had it do it once with the DSC on, only once with it off too come to think of it.

I've only ever had it do it on bumps, that's what seems to upset it?

I also expected it to be more taily than it is, in the wet it's border line scary but in the dry it doesn't seem to spit sideways as easy as I was expecting!

Regardless of the quirks I love my ute :beerchug:

I got a BA pursuit and it did tramp as its lowered but I have solved teh problem by making up 2 straps to hold the front of the leaf springs togeaher cost of about $5 and about 30min to do and works a treat... I'll post some pics up later

There seems to be alot of utes with this in the FG models bar the fortunate few of us.

I now have 33,000 on the clock and havent experienced once. Rears sit up in the guard

on 20's and still everything is sweet. Its been way overloaded a few times, 950 kg 6 times

or the usuall week day drive load of 3-400. It gets a hard time a fair bit and since 10,000

runs 340rwkw. I get it back on wednesday hopefully round the 400 mark but seem to mainly

be the manuals with this problem.
