WATCHPOINT: Testing for a seized front end is also easy. Place a jack in the front below the middle of the crosshead. Raise the jack until it makes contact with the bar. Now smoothly jack up watching the right stub axle. The springs should compress smoothly, without any hesitation before wheel rises at all. Lower the car and do the same procedure again watching the left stub axle. I suggest this test regularly. When you receive a new car, a rebuilt car, after long storage and every time you grease the car. Morgans can also have their front ends seize with accumulated grit , a hard knock and/or rust, aside from sloppy installlation workmanship. If these symptoms appear with a new car or one that has a newly rebuilt front, you must remove the front axles and increase the bush/kingpin clearance to .004-005". The deceiving element about these cars is that if you jack them and remove the weight from the front stub axles, they will most often seem perfect with no detectable problem in steering or up-and-down movement! The reason for this is simple. You have removed the effect of the weight and the chassis flex.
|COMMENT ON REAMING VERSUS HONING At one point in time, there was a debate over which was more better, hand reaming or machine honing. The goal was to create a grease holding surface and to obtain a prescion alignment and a, hopefully minimal clearance to allow for the longest possible front end life.. However, now, hardchrome kingpins prevent wear and annular grease grooves are cut into the bush inner surface. So who cares which method is used unless you are into mass production? You no longer need to balance off a minimal clearance against the risk of a seized front end and there is no need to be concered about grease adhesion.|
|WATCHPOINT: BEWARE YOUR NIPPLES! I have received many emails on the difficulties owners are having pumping grease into the stub axles in front. At first I thought it was the grease gun they chose, but I soon found the problem was even more basic. Many owners change the stub axle grease nipple (zirk) for angled ones which allow an easier time fitting their grease gun onto it. Sadly, they do not notice that the threaded portion of the Morgan grease nipples are very short..shorter than nipple normals. When they fit the new nipples they often thread them until they are forced into the kingpin. This blocks the flow of grease despite the use of eye-popping pressure. The front gets little of its needed grease feed and the kingpin can be damaged and movement prejudiced, even seized.|
