Potholes are a fact
of life. At this time of the year they the major cause of suspension, wheel
and tire damage. As a mechanic, I think they’re a great source of
business, however; here’s some helpful hints in avoiding damage. Try
to avoid hitting a pot hole with the steering turned. If possible drive
through with the wheels straight. Again if possible don’t apply the
brakes. Hitting the brakes will load the front suspension and reduce the
amount of travel available to absorb the impact. One more piece of
advice…..make sure your tires are inflated to the proper pressure.
Low pressure reduces the tire’s ability to absorb shock.
Recently I purchased tires from a local big box store. They offered to install them and charge them with nitrogen. Can you enlighten me on the use of nitrogen?
Nitrogen has been used to inflate tires in the racecars, aircraft and the trucking industry for years. Advantages include better control of air pressure with less loss due to seepage and less increase in pressure due to heat. Nitrogen is dry, this will eliminate corrosion problems inside the tire assembly and the lack of oxygen will also eliminate oxidation of the rubber and rim assembly. So why doesn’t everybody use the stuff? Well actually cost is the major stumbling block. Nitrogen generators currently list in the thousands and customers balk at paying for “air”.
I have a 1994 ford f-150 pickup truck with just under 100,000 km's... the automatic transmission sounds like a washboard when it shifts into the gear sequence... this transmission is equipped with overdrive and also has a button on the end of the shifter that when pushed enables the transmission to enter regular drive for hauling trailers etc. any suggestions ???
are designed to operate quietly. The noise that you are describing sounds
as if the gears are not meshing or a clutch is not engaging fast enough.
This usually is a sign of low internal pressure. Worn parts can cause low
pressure, as can a dirty transmission filter....Contact a competent
transmission shop and have the unit diagnosed. They will have to drop the
oil pan to inspect the transmission properly....
