Worse Rear Driveshaft Angle You Can Get by With in Tj

1. Steering wobble & rear drive shaft angle

   Hello there,

   I have 2004 TJ Rubicon. I have upgraded from 4 inch elevator to 5.five in the rear with heavy duty coils. In the front I accept added 1.v inch coil spacers. I am running 35inch Falkens.
   I also replaced upper rear control arms to adjustable once, so is rear and front end track confined.

   My problem is: I go into sway around 35-50 mph on whatsoever route and death wobble if I uneven pavement. Alignment and tire rest have been done (didn�t aid.) My front and rear axles are centered. I have tried to ready a pinion angle of rear drive shaft, it seams going higher angle helps, which is strange, because I don�t have yoke eliminator.

   I have longer driblet pitman arm I want to swap, then far had no luck removing PA nut... will attempt once more.

   Anyone tin can aid with suggestions?
   Some pics might help.

2. Steering wobble & rear drive shaft angle

   First
   DW is unremarkably due to a bad or loose track bar. Other bad components and alignments start the oscellation that continues untill the vehicle slows or stops. Classic DW starts at 65mph snd stops at 70mph.
   And then verify the track bar bolts and bushings are tight. The stock axel side bolt tin can be upgraded to a larger size.
   Then perform a dry steer test and identify any loose or failed components. Ball joints, TREs, wheel bearings, steering gear slop, control arm bushings...
   Fix what you notice loose.

   Second -alignment
   Did you get an alignment by a 4WD store???
   With lots of lift the target values change and most places practise not have the new targets.
   5 in of lift and adj command artillery to correct pinion bending will put caster beneath critical angle. This will allow yous will wander. Steering will be touchy & you will exist constant correcting your steering.
   Not having the rails bar and drag link parallel volition lead to crash-land steer when yous hit a pothole. And so DO NOT use a drib pitman arm, keep it stock.

   Wheel residuum and tire pressure make a difference in wander and DW. Do not over-inflate. Use the chalk method and keep pressures within iii-5 lbs of each other.

   Lifts above four in you may consider long artillery or mid arms to minimize shock and wear due to control arm angles.

   Third -driveline vibrations
   Now front and rear bulldoze shafts tin can cause vibrations but not normally DW. Check u-joints for slop and supersede if worn. Same for axel joints.
   See below graphic for correct setup based on driveshaft and joints you take.
   An engine elevator and/or lowering skid plate or low contour trans mount can assistance with angle adjustments.

3. Steering wobble & rear drive shaft bending

   BTW yous demand bump stops.

   And your front end sway bar links; 1 looks upside downwards. One side meridian is long the other the bottom is long.
