My D60 swap wanders all over the place but the truck has a burned out steering box... Hows the play in your steering box?
Well, I have almost zero play at the steering wheel so that tells me it's OK although I did have someone once tell me that doesn't mean the steering box isn't worn, but that makes no sense to me.
idk my one dana 50 truck drives like an arrow, where as my 250 with a dana 60 swap is straight-ish, but my 350 wanders all around
So it's not necessarily a d50 thing then.
I just completed (yesterday) my d60 swap, and yes, in my case it solved that problem completely. My TTB was spent, needed new everything including tie rods and ball joints and pivot bushings - and yes my truck wandered down the highway like a drunk sailor. Now steering and tracking is excellent, but FYI I put on a completely rebuilt D60 kingpin and all new tie rods, shocks and tires. twasn't cheap.
Yes, that's the wander I'm talking about, although yours sounds a bit worse than mine. So I may be looking at worn components, but from what I've read repairing the d50 is a bit like polishing a turd; at least where swapping in a 60 is an option. I did just replace the BFG Commercial A/Ts with Michelin LTX A/T2s and that helped a tiny bit. Shocks are still good.
...my 250 i swapped wandered bad but with spent ball joints and little tires it was crap. now with brand new ball joints, a 60, and 37s shes straight and narrow
So it sounds like a d60 rebuilt or in good condition will fix the problem unless the steering box is worn.
Alright then, I'm going to recheck the front end for anything that may be worn and move the d60 swap from the "one day" budget, to the "one day soon" budget. Thanks, all.
