Installation of a 2000 yr Buick Park Ave front wheel drive suspension Strut.This application is the same(1997-2006)for Park Ave Ultra(supercharge) Grand Prix Monte Carlo Regal Oldsmobile Bonneville.All W-Body and H-Body.Some Ultra are equip with electronic(wires at top of strut shaft) or air ride(Air line at the top of strut shaft) strut.
the knuckle on a strut-type suspension is mounted on the shock absorber. Sometime they are referred to as Macpherson strut. Strut type front suspension became popular on production cars in the 70′s because they offered a simple and inexpensive configuration that doesn’t take up much space. It is particularly well-suited to front-wheel-drive production cars, because it allows room for thr front drive-axle to pass through the front hub. Most of today’s small cars use this type of front suspension, because it is inexpensive and gives a fairly good ride quality with the compact dimension needed for front-wheel-drive cars.
DISADVANTAGE. Except where it might be required by the race-sanstioning bodies in production-based classes, such as showroom stock, it probably won’t be used on many race cars. One of the problems with a strut-type front suspension on a race car is that there isn’t much room for wide tires and wheels without increasing the scrub radius. Increasing the scrub radius causes a big increase in the side loading of the sliding members, which cause bending and higher friction loads. Another problem that concerns racers is that there is little camber gain possible with this type of front suspension, the swing arm lengh is reasonable and the roll center height and swing arm lengh, the lack of sufficient camber gain keeps this type of front suspension design from being suitable for race cars.
Another problem with a strut-type front suspension is that it requires a high cowl heigh to provide sufficient room for the tops of the struts. This can be a problem when building a low-profile race car. Honda has quit using strut-type suspension on its production cars for these same reason. They apparently feel that it is worth the increase cost to equip their car with superior double A-arm type of suspension.
Strut-type front suspension is used on some low-cost cars that offer high performance, but it is done to reduce cost, not for any handling advantage.
