My d-90 hops something fierce, especially on road in a turn. Any ideas on how to fix it? It seems like the front is the worst but it is hard to tell.

OME HDs all around with street tires, I am thinking about putting on some less lifted springs but I was also thinking about corrected arms but I am not sure if they will help.

PS anyone have some rear RRC springs they want to give away?

Could you describe what is happenning in more detail? Do you mean wheelhop under hard power? Or do you mean tire chirping while turning hard?

auto or not?


I get wheel hop too






































at the mall
:flipoff2:

:flipoff2:

mall ya ya ya I know, it does it offroad too, it is just much more noticable on.

The wheel literally hops. Catches jumps catches etc etc.

Hard power, it will not hook up even strait, on turns the front inside wheel hops really bad, even under moderate power.

My theory is that due to the change in suspension geometry due to the lift the wheels are hopping. Any commment?

94 5-speed

Sounds like the diff is locked to me...

AND

What in the he*l are you doing with street tires?!?:eek:

Yes, first make sure ALL three diffs are free and open. Jack up a wheel and rotate then do the other axle...

Second, the only reason I could see for wheel hop on power is worn bushings. If it is the front, it is probably the axle end radius arm bushings. But check all suspension links. Also make sure ALL bushing bolts are properly torqued. There is usually slop between the bolt and bush. If the bolts are not tight, it lets things move around.

You should not be anywhere near high enough to mess with the geometry to the point of causing this type of problem.

Diff is not locked (I am sure because you can tell when you do lock it is working and also with the diff locked it does NOT wheel hop, this is how I know one tire is losing traction and hopping), all bushings are fine and bolts tight on all suspension pieces.

It came with street tires, I can steal my wifes MTRs or the series SAGs if I need to go offroad. It is more of a driver, I can wheel the other ones.

My disco (5-speed) did not do it, but its pretty bad in the D90. I will drop it down closer to stock but only if it helps.

edit: I asked someone who used to be into comp-safari and he said that 90s were known to lift a front wheel but he had no real solution per se.

WTF?

The term comp-safari is used in the UK for competitive safari racing, it a type of racing involving landrovers and other 4wd machines according to what club you would be associated with, i hope it answers your WTF!!

Now from what i understand is the wheel hop only happens when cornering right??? seems to me that you might have a wieght transfer problem, as you corner the front inner wheel will lose grip as your suspension is streched to the limit of down ward travel while the opposite rear spring compresses down. If you drive it like you stole it round coners this will happen even with normal 90, remember it's a land rover not a subaru impreza wrx!;) Do you know what spring rates you are running?? Are the shocks long enough to accommodate the lift?? Are you sure the bushes are OK??

Gremlin

Maybe a bad shock?

umm

(huh?)

Look, there is something seriously wrong with your truck. You should never get wheel hop.

What spring do you have? Specific numbers please. Is the 90 a soft top, truck cab, CSW, details.........

Did you actually check your bushings?

Look jack the thing up. Check that ALL THREE diffs are free. Check that the suspension moves freely up and down. Check that there is ZERO play in the suspension links.....

Look, there is something seriously wrong with your truck

Yep. The only way I see this happening is if you have a rear full time locker and you have somehow lost all power to the front end AND you are getting binding in the front end. This really should not be happening. Check the front bushings again. Other than that, are you sure it is a D-90? Maybe you are driving a TJ :confused:

If you run heavy springs rates and don't have enough weight in the truck you can generate some "hop". This also shows up on corrugations on dirt roads where the rear wheels will just bounce across the top of the corrugations and the truck will try and swap ends. This is always more noticeable on shorter wheelbases.
I'm not sure what the engineering principle for it is (downforce?) but it's easy to check. Just stick some weight in the truck and try the same corner. You'll probably find the additional weight wil make the truck handle a lot better.
If that is the case then you have three choices. Swap the springs for lighter rates (but the same length to keep your lift), or buy lots of heavy bling bling accessories, winch, rollcage, bullbar, etc, or eat a lot more and get some much bigger friends. :flipoff2:
An OME 764 (approx 230 pound) in the rear of an unladen 90 stationwagon will generate this effect. What springs are you running and what weight is your truck carrying?

(OME 764s are at 220...751s are at 230...:flipoff2: )

I heard about a mid-90's Land Rover Service Bulletin addressing the wheel-hop issue and warning it was a strong precursor for the front axle falling off. I wouldn't drive that rig if I were you.

Me too...

I always lift a front wheel attacking round abouts... Yes I go too fast - the speed limit is 50km/hr after all...

Happens to me mostly because of weight transfer from the lift and too soft springs in the rear so that the Rangie "sits down" on its left rear lifting the front right. Remember its a right hand drive kids...

Its alarming at first but kinda fun when you get used to it - stops people from pulling out in front of you as it looks like you are gonna roll on top of them.....

I checked everything, I am convinced it is the spring rates and possibly the shock bottoming out (kinda doubt it)

I am going to swap out the springs for some, longer softer ones and see what happens.

Thanks
