Id say its suspension for the wheel hop... but for that one guy who said when he burns the tires only one wheel spins, sounds like your lsd is dead

 

Previously people have mentioned that it could be suspension problem. More specifically if you have 1 or both shocks going bad on the rear it will cause terrible wheel hop. And there is no way to just look at a shock/strut and tell if it is bad (unless it is SO bad it is leaking oil at the shaft).

I have no explination for the clunking noise you get when crossing train tracks. The "dog bone" links are a normal item to have to replace on a FC and will cause a bad bumping noise. It might or not be related to the wheel hop.

Be warned wheel hop can cause extensive damage. As the wheel is hopping the drivetrain is getting (grip, nogrip, grip, nogrip, grip, nogrip, etc.) and that will lead to broken axels, broken rear end, broken universal joints and in the worst case a broken transmission.

 

Thanks fellas i appreciate the help. Looks like when iget my 84 up i am going to have to go through the 90s suspension. But thats a good thing .

 

Thanks for you help, yah i think my lsd is shot too...
funny thing though, i jacked my car up yesterday before i put it away, and spun the left rear tire. The right rear tire turned and kept pace. IE stopped rolling, the other stopped. So when i jack that car up it spins the same way. thats with no load on the other tire. I wonder if i got a friend to hold it, then tried to turn, if it might **** up like it does on the road....

well looks like this winter is going to be expensive for 1 HS student

where are these dog bone links?

 

Here is the diagram of them from the FSM. They are properly called "Rear Control Links".

I guess time for some new shocks

 

i can chirp second loud and third has a little chirp. Anyone else chirp into third?

 

not for nuthin but I replaced my rear struts(stock springs) in my T2 and when I launch incorrectly I still get wheelhop. When I drag race I chirp everygear with 235 Michelen Pilot MXX3's. But on the street I pretty much follow the rules so I couldnt tell you about them on the street.

 

for a while i got mine to chirp into 3rd. now i cant seem to chirp then into 1st. i need a new suspension

 

I Okay *UPDATE* I just installed my new agx struts going to install the springs next, but the struts did not solve the wheel hop, I haven't adjusted them yet so that may be the problem, I have chirped in 2nd and 3rd too, I'm thinking it maybe some bushing, or the dog bone links, I'm gonna jack up my car and take a look any other suggestions?

 

try launching lower or slipping the clutch more. I spin the tires over at anything above 2500rpm off the line. But then I actually connect hard enough in second to force the afm flapper back to read 100% capacity on the s-afc and she chokes. It's not a short, the graph reads sloped as the flapper travels back to max. Sucks to have so much power.... lol gets expensive to keep up with it.

 

no no, if I give it more power by slipping the clutch (which isn't good for racing or at all for that matter) it just gets more violent

 

in my old car it would hop if I let the clutch go under 4k, but at anything over that it would just smoke 'em up

 

yes as in my old car my GTU did that too, but this is a thumping noise after I shift in to second and instead of chirping like they used to feels like the right side chirps but the left side hops, gonna look under it tommorrow
