Thrust Misalignment after Leaf Spring Install

Hey Guys

Just recently installed my new Dobinson L59-110-R leaf pac's. I was initially quite satisfied with the results until I noticed a slight handling issue that wasn't there before the install. Since I was under the impression that alignment issues weren't expected with leaf installations, I was quite surprised when I discovered that I might have an issue. After researching thrust alignment issues related to leaf spring applications, I took some measurements underneath the vehicle attempting to verify my suspicions. And soon discovered that my suspicions could be correct.

I attempted to correct the misalignment issue as best I could by reexamining the installation process. But I didn't really find any issues that were outstanding in the mounts. Since I couldn't physically move the axle by hand even after loosening all the mounts, I used a couple of ratchet straps to force the axle in the direction of alignment needed while loose. Then tightened everything up while the pressure was applied. The end results turned out favorable. But I don't believe that it turned out perfect. I have an alignment scheduled for Tuesday and anxiously awaiting the results.

Any thoughts from the forum?

 

May sound dumb. But they are installed in the same direction correct? Or not backwards?

 

Yes. I made an extra effort to confirm orientation because I decided to go with OE rubber bushings instead of Poly Bushings. The OE bushings take a little more effort to install. I didn't want to take a chance on having to un-install them.

Thank You for your reply.

 

Fairly common. There is enough room in the centering pin and axle interface to get .25” difference. Have had it happen on my truck and another when I was doing leaf spring work.

 

I used a ratchet strap around the axle and hooked to the frame on one side to help center it. Loosen the u bolts of course. There's hardly any adjustment to made but there is some, worked for me

Thanks Guys. I used the strap method also. From my best efforts using a tape measure, I started out just under 1/4" out on the passenger side. I've managed to get it down to about 1/16 out on the passenger side using the strap method. Still have a drift that requires slight pressure on the wheel to compensate. I feel confident that an alignment will make the problem go away. But I'll be very upset if the "crabbing" is noticeable from the outside.

 

If you are that close I think you’ll be fine once the alignment is done.

 

Drives much better. I don't really understand how to read it.
