Is shudder usually associated with the rear?

I'm looking to have the TSB done in the rear and just level the front with Billisteins..maybe .75 to 1.5.

I was just worried about having issues with shudder and figured I'd let the dealer do the TSB first and have them deal with any shudder issues after the install. (Though I've searched and haven't seen anyone have issues after the TSB.)

Then I'll lift the front once I know the rear is fine. Are there any potential issues with shudder emanating from the front? I have a lifted Wrangler and rear vibs are inevitable but easy to address. Vibs from the front are much more of a mess.

Any thoughts?

 

i was told by my 4wd place that the rear springs are too soft and causes the shudder.(most of the times)

 

Depends on the situation.... and every situation is different.

These trucks are IFS and it's a whole different ball game from a solid front axle Wrangler.....in terms of troubleshooting drivability & shudder issues.

Get the TSB done and go from there. The TSB should include an allignment, so atleast you can cross that off your list of things that 'should' be done to help diagnose issues.
