Which kit did you buy from them?
Not sure and did you let them know it was going on a CRD?
You can't lift a CRD as high as a gasser so if the wrong lift then there can be part of the problem
Also the CRD of course has the front diff closer to the drivers side which has a shorter CV on that side resulting in being hard to get the lift on.
IF it is the right kit them wrap the CV boot with heavy rags and use rachet straps one per side on the clevis to pull it over into place.
Good luck with using RRO
