Yes, it is grammatically correct. 'Spline' is a transitive verb meaning 'to put splines on'. Therefore, something onto which splines are put can be referred to as 'splined'.
A slip yoke has a splined shaft the drive shaft slides over. This allows the drive shaft to flex on rough terrain. A flange yoke has a flat plate on the transfer case and the end of the drive shaft and they bolt together.
Unless you see some sort of set screw or locking ring, it screws off. Actually on a ford you must pull them off. they have a press fit. The shaft is splined and the knob is pressed onto the shaft.
First make drive shaft and yoke to insure tat they are replaced in the same location to maintain factory balance Remove small "U" bolts at yoke Pry drive shaft out of yoke Pull driveshaft off splined end
If you are talking about the splined ring around the input shaft, it's for the torque converter stator. The stator is like a second set of fan blades inside the converter that redirect fluid to the blades that turn the input shaft. It greatly increases the efficiency of the torque converter, which is actually a fluid coupling. In order to do it's job, the stator must be held stationary, that's what the splined ring is for. Hope that makes sense. It's not easy to explain.
Remove the plastic caps on the Astra wiper arm. There is a nut under the cap, remove it. The arm will now slide off of the splined shaft.
the wiper arms are on a splined shaft so you would have to remove the arm from the shaft and rotate and replace them farther to the left or right to get the position you want most arms are held with a clip device of some kind that is part of the arm its self
Rear brake. There is a little nut an bolt on the trans. shaft. This tightens the arm to the splined shaft. Take off the bolt, and wiggle it off. You can use a screw driver to help. this is a 1980 and has a washer and cotter pin holding it on the shaft with the spring, just can't seem to get it loose
looking for parts for a old ariens tiller the gear that rides on the worm that runs tines the shaft is splined where gear sits
the wiper arm is pressed on to a splined shaft. the shaft or the arm could be stripped. you need to remove the arm and see if the motor is still turning the shaft and to check the splines.
