Also how do i fix it? body shop? thanks
You can take it to a wheel alignment place.
Do a 4 wheel alignment and that will show if the rear and front aren't in alignment.
Or a frame shop... /forums/images/graemlins/smile.gif
What makes you think it's bent?
start taking measurements... fore and aft... there is a body book that tells where the measurement holes are but you can just pick the same ones on both sides of the frame and measure in a x..... if the x isnt equal .. you have something out of whack... you can also measure frame to ground keeping in mind there are suspension anomolies that can muddy this check...
the frame shop has a machine that checks this same square... but with more parameters and with a known variable.. i.e they calibrate their machine to be square...
now the previous post asking you why you think it might not be squre is also right on...
is it not tracking straight?... (did someone following you tell you your truck is "crabbing" down the road... sure sign of a heavy previous t/c)
or perhaps did you....
drive it off a cliff... into a tree.. or all the other things ck5ers seem to do to their rigs from time to time
hope this helps
you want a shop that has a frame machine not just an alignment machine and someone that understands bent metal... not some mechanic that aligns toyotas
If someone told you that your truck is not running straight it is a good idea to check it out.
Just remember that the rear axle in this year of vehicle is not as wide as the front. This will make the truck look as if it is "dog tracking" if viewed from the rear.
An easy but not very accurate way is to measure from spring perch to spring perch in a X fashion.
This is not the most technical or accurate but it will give you an idea if the frame has been pushed into a diamond shape. That is one side of the frame is farther back than the other.
You can do this on the bottom of the axle using the U bolts. While you are down there take a look at the front shackles make sure they look nice and straight.(that is side to side not front to back)
If you are checking the frame because your steering feels loose or washy then make sure the frame is not damaged at the steering box area. This type of truck is notorius for small unseen cracks in this area.
He thinks it not tracking right. That is what he said. Hard to tell in my yard not one smooth place. The under the truck is all banged up. oil pan is hit up, but I never noticed the rest of it to just now. Its kind of hard to miss to. Then all the body lines are messed up. Nothing is even. Thanks for the help Mike
