4'' lift: front driveshaft too short: ideas

[FlatBlackBurb]

okay so I just put a 4'' suspension lift on my '87 3/4 suburban and we got done lifting it and the front driveshaft is too short by about an inch. should i just get a spacer? ive talked with a bunch of people and they all gave me a weird sideways look and said "4 inches? that shouldn't be a problem". can i stick a grease gun in there and lube it up some? or should i be able to just hammer it out more? how fragile are driveshafts

Drive shafts are pretty tough but you shouldnt need to hammer anything out. With my front shaft I did take off the dust cap and clean out the old grease that had gummed up in there, that gave me the shafts full travel. the other solution is to have it lengthened. Its not that expensive and makes much more sense than a spacer.

I'm telling you dude, grease it and see if itll go out more. Dont bother asking again and again without trying that...if it doesnt get a spacer

did you drop the t-case?

 

[4xcrazy]

the driveshaft WILL expand more, just have to motivate it too...

and you DON'T have to drop the t-case on a Burb

It will go. I had to heat and hammer mine out, but thats b/c the thing had never been greased before. 4" on sub with a 700r4 needs no driveshaft mods, Im proof

Same here, on my '89 Burb 4" 700/241 no probs.
