installing SYE and CV

I have an SYE and CV driveshaft coming in tomorrow but my lift won't be here till next week sometime, maybe. I'm guessing I cannot install my SYE and CV driveshaft until I have rear upper adjustable arms from my lift because I won't be able to set the correct rear axle angle? Is this correct? I would like to be able to go ahead and install the SYE and CV this weekend so all I will have to do when I get the lift is put it on. In other words, I can't wait to do something to this thing.

Does anyone know if I can install the SYE and CV driveshaft on a jeep with stock suspension without problems until my lift arrives?

You don't really want to install it until after the lift. That way you get the correct length driveshaft for the lift.

yes the above is true, but if you have the right cv driveshaft length you should be able to install it, then extend it as needed

I measured last week for the driveshaft and sent it to Tom Wood along with the specific lift I am installing. He is supposed to know what length I will need after the lift. The CV is coming today with the SYE. So would it be better to just wait until after the lift is on? Or since I should have the correct length drive stick, it would be ok to go ahead and slap that in there?

You said he gave you a drive shaft for with the lift kit on. It depends on the size of the lift kit. If it is a 2.5" maybe you can, but if it is a 4" or more I wouldn't do it as the fully compressed size of the drive shaft could be to long and you would break it before you even get the lift. If you have another car go ahead and install it just don't drive it till the lift gets installed. I understand the SYE kit is a little involved and would be easier to do over a weekend than a weekday. It is suggested that you completely remove the t-case though it is not "required". If you don't have another vehicle wait for the lift, it's not worth breaking something over.

Something else you could do is install it and just don't put on the rear driveshaft and drive around(short distances) in 4wd(really 2wd without rear DS)

You can't run the new CV driveshaft until you have raised the rear axle's pinion angle to the new proper (higher) angle. If you do, you'll experience severe vibrations which can damage the new CV driveshaft's u-joints, not to mention the seals on the axle and t-case. The only way you can raise the pinion angle is via the adjustable length control arms that are part of your new suspension lift.
When you have a choice, buy American.

I was under the assumption after he installed the SYE/DS that he wouldnt drive it until he installed the serious
