Jackstands under the axel as I have the rear wheels off right nowIs the top shot suspension loaded or unloaded?
Explain GaryYou wouldn't want that drive shaft being any longer than it is.
I have an inch & a half.You want there to be some ability to slide in and out, right now you have about an inch it can go in before it will bottom out under heavy acceleration. It could probably do with a bit more being you have a 440 in the vehicle. Under heavy acceleration the rear axle is going to push forward a bit sliding the drive shift further into the transmission.
I would leave it at that and see how it goes, keep an ear out for any clunks under hard acceleration, if so, back off quick then think about taking another half inch out of it.I have an inch & a half.
Yep that what I plan to do.I would leave it at that and see how it goes, keep an ear out for any clunks under hard acceleration, if so, back off quick then think about taking another half inch out of it.
View attachment 123049 View attachment 123050 View attachment 123051 Ok on my D440 truck project I had a took my driveshaft to a local driveshaft shop. Told him it was too short & I needed 52 inches center to center. He wrote it on the driveshaft in that yellow marker. He called this morning & said it was ready. Picked it up & never gave it a moments though to measure it. Got home & decided to pull a tape & its 51 1/2 center to center. Called him up. He couldn't believe he had cut the tube too short. Told me to try it & if I won't happy he'd make it right. Also he said he balanced it yet I see no weights. There is a lot of welding slag on it & what looks to me to be sloppy welds. I think he got in a hurry. Anyway. Here's pics of the ends & a pic of it installed. Opinions please. Is this safe to run. It's a 440 pick up with 3.91 sure grip. Also it looks like I have 2 1/2 inches of spline engagement & another 1 1/2 of non splined engagement
The fact that they are a driveshaft shop and gave you a shaft with welds like that is concern but other than sloppy it looks okay you can't really v it in and have it lay perfectly flat because the tube is only .090 and divits next to the bead would reduce the thickness even more.I am a little worried about the welds. This is a drive shaft shop
I agree.they... gave you a shaft with welds like that
