Jeep Grand Cherokee in limp mode

Customer Question

Having problems with my Jeep Grand Cherokee

Here is what I have done to date and desperately need help to get the Jeep going again

April 4 fitted new brake shoes, Lower control arms, steering outer tie rods, Took front springs out and installed on the correct side.

To access the left hand side strut mounts I uncliped the power distribution centre and lifted it up on its edge placing some strain

on the wiring where it entered the power distribution centre.

By Tire shop

Fitted bigger tires 265/70/R17 and wheel alignment

April 21 2015  ESP BAS and traction lights on
