Death Wobble Help!!
I have 99 wj. I have done a lot of research on death wobble and I can't find another situation that is similar to mine. I first experienced death wobble when I had the old longblock in the back of my jeep and I was going about 55mph and coming to stop, the death wobble happened when I pushed on the breaks going about 55 mph and shock the whole jeep scared the ***** on of me. So I thought the weight of the longblock was causeing the death wobble so I took the LB out of the back and I still had the DW but was not as bad.
So i read up on the internet that loose steering parts cause DW. So crawled under the jeep to find that I had play in the inner right side of the tie rod, but I could also take both the drag link and tie rod bar turn them clockwise and counter clock wise and I could turn them enough to make make them clunk. But some people say that is normal and some say replace them. I also found that my rear upper suspension arm bushing is bad. I replaced the inner right tie rod end, I have not replace the bushing yet because I read the dw only deals with the front of the vehicle. When I had the tie off I checked to see if the there was play in the rotor at the 6 and 12 position no movement so I checked the 3 and 9 position no movement I shook the jeep hard enough to move the whole jeep and I checked both sides no movement.
Went for a drive and I still have death wobble but the dw is alot less now. I still only get dw when I am breaking at about 55 mph. Now people also say to check your toe since I have installed a new tie rod end, I check it and the toe was at about +1/8 or less I have to adjust the tie rod end down some more to about -1/8 as that is what people say is the best toe in setting. Would a toe of +1/8 still becausing the dw. I have also noticed that SS looks like it is leaking oil very slow, but I thought the ss is just a band aid and that you can drive with out one, so I didn't think the ss is the problem. The track bar is another thing to check, so I did and I can barely get the track bar to move. All the bushing on the control arms look to be ok except the lower control arm bushing that is on the passenger side that bushing has a crack in it. Put none of the control arms have movement.
But if I start to slow down before hand and get below 50 mph I can slam on the breaks and won't experience the dw. So I thought I might have warped rotors that is trigging the dw, but If i had warped rotors wouldn't I have shaking when i break at any speed. When i press the breaks at slower speed the wheel doesn't shake. So i thought that ruled out having wrapped rotors.
So what do you think is the problem? The dw still only happens at about 55mph and when I am breaking hard and when I let off the breaks the dw still occurs until I slow down to about 35mpg then.
My jeep is completely stock.
