lifted EA82 wagon.. rear wheel hop...

[torxxx]

So I decided to put the petal to the floor tonite on the drive home since it warmed up. Roads are slick as hell, had a blast driving home from work drifting in and out of traffic on the highway. made me realize that I need more WRC style driving practice year around so I dont get rusty during the summer time.

 

Anyhow, VLSD chunk in the rear diff of my wagon with my little 93 hp modified Ea82 Carb rig. (might even be 93.5 hp now. put some stickers on it last week lol)

 

I'm noticing nasty wheel hop 1st through 3rd gear when I spin out leaving an intersection. I dont remember the car ever having that problem before on the ice. I've had 3 diff VLSD's in it in the last 6 years. two died from too much water getting in the diff and me being too lazy to drain it. Kept this one out of the water all summer changed the fluid to Mobil 1 gear/diff oil and squirted in my tube of magic LSD cream.

 

I dont have sway bars on my rig, matter of fact I refuse to put them on since they limit suspension movement. when you only have 5 inches of travel, you wanna use all 5 inches.. (god that makes me think of something dirty, but I'll refuse to say it for SubaruJunkies sake. dont wanna hurt his feelings)

 

What solutions do I have for this wheel hop? Brand new struts on the rear, new accord springs. Both installed in the last 6 months. Maybe the VLSD is locking up sooner than it usually does and thats causing wheel hop? I'm just trying to figure out a way to fix it or stop it from happening because I really dont want my springs blowing off the bottom spring mount AGAIN. I have GL-10 control arms in the rear that have the sway bar link attachment points.. wondering if I should bolt one on just for the winter and take it off in the summer?

 

What do you guys think?

Cant hurt my feelings. My rig has a tad bit more than 5" of flex

 

 

 

I'm going to say the problem is no-swaybars. Or crappy tires.

It could be a malfunctioning VLSD, like its working like ABS, only backwards, which isnt cool. Also, on a side note, VLSD are sealed units, IIRC you dont need to add LSD additives to the diff fluid.

 

Other than that, I dont have any ideas

not sure about it being sealed Bill. Last service I didnt put it in and it chattered like a spring type LSD did. made all sorts of strange noises..

[presslab]

Yeah I was under the impression that the VLSD chunk was sealed with it's magic fluid inside, and the fluid added to the diff was just for the R&P.

 

I have a clutch LSD in my EA82T. It's stock height, XT6 sways, 4EAT AWD, BFG g-Force T/A KD tires. I have zero hop, ever. I've never had it dyno'd, but I'm running a TD04 with 1 BAR of boost, so it's pretty powerful.

 

Sorry, that probably doesn't help too much, just a data point...

 

What kind of transaxle do you have? I assume you're driving it 4-hi?

 

I'm going to guess that because you are lifted with the Accord springs, that the torque of the axles makes your suspension load up; the tire then slips and your suspension unloads, over and over.

[torxxx]

yes in 4 hi.

 

The amount of weight in the rear of my car should stop wheel hop. 200 lb speaker box, 3 tool boxes, spare alternators, water pump few gal. of antifreeze 2 spare tires etc. prolly 500 lbs of stuff sitting right on the rear struts. The lift is 3 inch strut spacers and then 1-2 inches with the springs.
