Help with death wobble

I recently installed the Full Traction 3" economy lift with full traction shocks. It was fine with the stock wheels and Tires on. Now that i have the interco thornbird 33x10.50x15 on the stock wheels it starts to death wobble around 50-60mph. this is after i had the wheels alignment. the guy said the tires are causing it? I would like to get rid of these tires and get something less extreme, such as 32's that are quiter on the road if you have a tire suggesstion let me know. any help would be great here are some pics.

is the front track bar tight? (1 bolt at axle and the other bolt at chassis)...

My guess is going to be your tires. Interco tires, especially Thornbirds are horrible balancers.

Get some BFG-A/T's

get an all terrain but if you like an aggressive looking tire that grips good on and off road get the pro comp xterrains they are about as quiet as bfg all xterrains but you wont get the mileage as the all terrain

a friend bought the bfg all terrains and got rid of them after 3 weeks off use (he hated not having the traction off road)
he put the xterrains on and is very happy with them

But if you drive a mall crawler then get an all terrain

Rotate your tires around and see if you can move the tires with the least amount of weights on them to the front. That is what I had to do to my set up. I also have the FT 3" lift. I am running the Goodyear MT/R's 33X12.50X15 and they are great on the road and excellent off road, more so on rocks.

I highly recommend the XTerrains!! I took off a worn out set of 33" BFG AT's and had a better ride with the 35" XTerrains and they are really tough looking!! I haven't had a chance to test them offroad yet, but I can't wait to try!!

you need to make sure your tires (as Jerry would say) are perfectly balanced.

thornbirds suck

looks like one hell of a parking lot of a mall.

BFG's are one of the best all around tire. Mud tires get noisy as they wear out.

I have the 3" full traction on my lj with 32x11.5 bfg mt's and get no death wobble so my guess would also be your tires. good luck.

I run the 3" FT lift with 33" BFG AT's. Try rotating your tires.

I got a great deal at 4wheel parts. However, tires are the only thing I will buy from them. Their suspension stuff is crap.

the problem that Ive had with bfg is the allterrain doesnt give me any traction off road and both the bfg allterrain and mud terrains I go through side walls every trip out

the pro comp xtrrain might not get 50,000 miles like an allterrain but it is just as qiet on road I got 25,000 miles out of my xterrains and I run a spool in my d44
I also think the traction off road was far more supierior off road to

THE DEATH-WOBBLE!!!!! Utter-Sweet Harmonics only percieved as.........Kidding!!!!!!

Your 33/10.5's and your lift is such a common store-bought after-market upgrade!!!!
By process of elimination...........

1. Tire unbalanced or defect
2. Check tire pressure.
3. Low pwr-steering fluid
4. Worn steering-stabilizer
5. Worn ball-joint or tie-rod ends

[QUOTE=Chad P;165468]How many ply are the sidewall on pro-comps

even though the bfg side wall is a tree ply the procomp sidewall is thicker
even though its only a thick 2 ply scuff and tear resistant sidewall
I compared the thickness before I bought my 33's

I no longer run procomp because I went to a 35 and got the tires really cheap
( I'm glade I didnt buy these tires new I would be pissed If I payed $160 a tire and the first time I run them the lugs tear off )

We have alot of rocks here. I am not a fan of the tread design of the pro comps.

I am waiting for BFG to come out with the BGF M/T KM2's in a 33x12.50R15

BFG are quite the folks

what a bunch of idiots

"lots of new multiple various sizes!" is there description...this is the biggest load of horse dung i have ever heard. they don't even have them for a 15" wheel which is what the majority of jeepers run. and i don't think i saw 33" either. talking about the new mud terrain.

So what could be wrong if it wobbles bad on one day at around 55-60 mph and doesn't the next day. I didn't do anything to it and it corrected itself. Maybe she was upset with me for some reason. Kinda like the day I took the back seat out and got a rash. She was screwing with me.

Wow. Tons of bad information in this thread.

Tires do not cause death wobble. They only excite the other problems in your solid axle front end. You need to fix the other problems in your front suspension.

Then ditch the thornbirds just because they suck! But they are not your problem.

I would hardly toss BFG in the idiot category. Just because they are not currently making a tire you probably wouldn't buy anyways doesn't mean they won't make it in the near future. Before you sling mud in their face you should research their company a bit more and find out exactly how much they do for the sport you stand up for so much.

BFG is instrumental in helping keep wheelin areas open. They are in the lime light with almost every off road event. They help keep this sport going with a "corporate" presence and stand up for the little guy. Above and beyond what they do to help us stay open for business they also incorporate one of THE best tires in this sport. Just because you aren't set up to run them doesn't mean their products suck or they are of feeble mind.

i was exaggerating (sp?). i do not think they are idiots. i just think their description of "new multiple sizes" is a load of horse crap. at least right now. and for you to say that i would probably not purchase them is invalid too. because i own bfg mud terrains right now and would consider purchasing them as my next tire if the price and size is right. I shouldn't have said BFG is stupid. They are not. But i DO think that their description is absolute crap and lies! I believe that they will come out with the sizes for jeeps which is great and they make great products (i run them) but their "new multiple size" description is junk! most jeepers can't run the sizes they have now.

well answer me this my last set of tires I had no wobble everything was smooth but the crappy tires I had before there was some wobble about 45
now that I have a different set of tires on I have that wobble back
(BUT it isn't death wobble its just a wobble in the front end and what I gather he is getting is the same wobble except its at 55 (he states that it starts to death wobble)
so to me it sounds like it is starting to give him a little steering wheel wobble at 55

if it is death wobble he would most likely have to slow down or stop before the jeep stops shaking which will also scare the $#!*& out of you and he would probably have to change his pants after that
