only thing ot worry about on he H052 and 72 models is the price of brake parts if even available, and also keep eye on pinion stem bearing, they liek to burn up if fluid drops just low enough, keep tight tabs on that oil level in that axle! make sure the pinion yoke and stem does not move side to side when you get udner there and yank away on it, yank and push hard ot make sure !
