Gotta Death Wobble - Gonna Start w/ new Tires
 
I think my wobble is due to really bad alignment which has caused my tires to wear WAY uneven.

So I want to replace the tires. My current tires are Goodyear
225 75R15.

Can someone recommend a 31" tire that my stock 15" wheels will fit on?

Or possibly a link for a good wheel/tire combo? I thought Quadratec offered combos but I cant find them on their website.

Thanks ya'll!

I have a 2003 Wrangler - can I put 31" tires on the stock 15" wheels?

I am also looking for a tire that is good looking but yet affordable for my recently purchased 2004 Sahara. These tires will be used 98% on pavement. Wanting 31 x 10.5 x 15. Any help would be greatly appreciated.

My reccomendation is BFG all terrain. They will last forever. They will fit on a stock jeep with minor rubbing when you turn the steering wheel all the way to one side.

I just bought a 2002 wrangler sport with a 1.75 inch lift kit. The tires on it now are Michelin LT 31x10.5x15. I know the tires need replacement but the front end seems to want to drift and my wife says it feels top heavy. What do you recommend?

Thanks for the hi-jacking. Much appreciated.

I would get an alignment and check your steering components up front to see if anything is loose.

Calm down man lol, everyones new at one time. What other questions did you have? I would recommend going with a new wheel because they are relativley cheap and with the proper backspacing you wont rub at all with 31's. You then just have to be careful about fender coverage laws in your state.

Make sure you check front end stuff before going to drop $$ on tires. The tires might be the issue also many other things. Just check to see everything is OK:)

Assuming you have a TJ and not a YJ Wrangler, you can easily run 31x10.50 tires on your 15" wheels without issue.

So far as your DW is concerned, make sure your trackbar mounting bolt (at the axle end) is tight and its mounting bolt holes are not wallowed out. If the trackbar can move at all (it can be too loose even if you can't move it with your hands), it can allow DW to develop after being triggered by something like out of balance tires, bump in the road, bad (loose) ball joints or unit bearing hub, etc.

There's a nice FAQ on Death Wobble at the top of the TJ Jeep Wrangler Tech forum. :)

Im not sure I understand...I need the tires regardless. The current ones are worn sideways and Im driving 1200 miles on Saturday (Philly to FL).

The front end could be out of wack...I still need to get tires and alignment regardless.

You do, but if the front end is out of wack the tires can still wear uneven and you still can get death wobble.

It's been pouring rain here in Philly so I haven't been able to get under the Jeep (on dry ground) to inspect the front end. So I did something blasphemous...I took my CBR out of the garage and put it in the rain, along with a LOT of other stuff, so now I can fit the front end of the Jeep in to the garage. Im not that great with this stuff, so Im hoping to be able to AT LEAST point my mechanic in the right direction.

Since all I ever do is ask questions, Im going to try to make a contribution to the other mechanically challenged folks out there by posting a diagram of the front end of the Jeep. This way, if we have questions about something that may be a DW culprit, we can ask it in an intelligent manner (instead of, "Hey, the bolt that attaches the short shiny bar to the long rusty bar seems a little loose...any ideas?").

Hopefully this helps someone. By the way, this isn't my write-up so I dont take credit (or blame) for what is here. I got it from a Jeeper on another blog. If anyone wants to add what we should be looking for, feel free.

Tips for inspecting front end issues relating to shimmies or DW:

Consider:
1. Control arm bushings - if they are worn, you may get play in the axle.
2. Tie rod ends - ensure greased, intact, and no lateral movement (may have some rotation due to the joint type).
3. Track bar - check BOTH ends (frame and axle)
4. CV joints - jack tire up and check for motion top to bottom /\ kinda thing.
5. Draglink/tie rod. make sure that connection is secure as well.

If the problem has cropped up, you should also ensure your tires are properly balanced and have even wear.

IF you replace the steering stabilizer/dampener, I'd suggest at least getting a good aftermarket one, like Old Man Emu or something. That stock unit is so so. That will be my next acquisition.

If you look at this pic, you can see the primary components for the front suspension. Any of those points being loose can create havoc.

^^X2. I understand you need tires but like we said you still need to check if everything else is OK, because if it's not it would still be bad for the tires.

I got the tires and so far (50 miles) it took away the death wobble and most shimmies too. I went out and got some automotive degreaser/cleaner - I couldn't see most of the connection points on the suspension to determine if anything is worn.

cougforester 07-31-2009 09:55 PM

for what it's worth this long after the original post - my 06 unlimited developed this same thing out of the blue. a balance of all four tires cured it.

TheBostonWrangler 08-06-2009 10:33 PM

1500 miles and not a SINGLE death wobble!!!

To anyone with DW - if you are due for tires and/or alignment, start there first. I could have driven myself crazy searching for a suspension issue when it wasn't necessary.
