Correct. It is splined both ends. 2 person method and from memory so some details 10/10 cloudy. Check normal procedure in Bentley or similar. Scribe around bearing housing accurately so you can reposition accurately and not stuff wheel alignment. Think it was still necessary to remove bolts securing housing to spring plate to allow enough movement off torsion bar. Advantage of 2 people meant didn't have to remove brakes or brake lines ? Were held in place. Careful with old brake lines as most are corroded and ready to snap. Think you may have replaced yours on one kombi already? I gently applied pressure with a lever between plate and housing while tapping torsion bar in with a drift to ensure it didn't come off the inner spline. Previously marked spline positions with centre punch and marker pen as per normal procedure for such. If you have lowered the kombi there may be no pressure with arm on bottom stop. If not then support the lower end on a trolley jack. It only drops about a cm under tension once clear of housing. Slide off and and support, clean any deposited rubber. Talc and install new rubber bush. Carefuly align and refit. Nudging lower end of plate can assist getting bolts to line up. Check Ricks post on refitting same.
