What does it exactly do? My OEM bushings are shot on my 03, was recommended to change them to whiteline, can anyone give me there take on this please?

I have the same problem.
A shop I go to quoted me 280 for a new set with labor. And Idk if that's about right. Since they do need to take off the exhaust and what not.

Wait, is 280 including the bushing part?
I got quoted 300 labor plus bushings, god damn, its really annoying man. As soon as I fix one problem I find out another. especially during the beginning of the college semester when I have to pay tuition

The bushings keep your diff from wobbling around. Its more probable that the front 2 bushings are still fine. Don't expect the labor to be very cheap since the rear bushing can't be pressed out as easily as the rest.

sorry it was actually 300 for all of it including the bushings.
But yeah i have the same problem, i need a new brake kit and some shocks -.- kinda burning holes in my wallet at the moment. Lol

Rear Differential Kit - WHITELINE

$99 for bushings and $200 for labor. Labor is 2-3 hours. You have to remove the differential, cut out the old bushing, and install the new one. The front diff ones can just be pounded/pressed out.

You can probably drive around on the rear bushing being bad for a while - it wont be too critical, but should be replaced when you can.

I highly recommend all of the WHITELINE bushings. I sell them only because I use them and love them. Designed very well.

i happened to get mine for cheap from a member.
If you have moderate skills on working on your vehicle, DIY
I read it would take a whole day and blah blah blah.
You just need a drill with a couple bits and a sawz all with a metal blade
took me about 3 hours in my driveway
