In Missouri, Illinois and Indiana there is a heavy truck service company called Truck Centers Inc. They have 12 locations along I-70, I-64, I-55 and I-57. I scheduled an appointment with them to have our coach front end aligned and caster set to 6 degrees. Also, I asked them to install the plugs and wires I purchased from Brazels Ultra RV. They did excellent work and recommend them if you are in the Midwest. https://www.truckcentersinc.com/
I had a nice 75 mile drive home to feel the results.
- Alignment and Caster made a huge improvement in front wheel tracking. Much improved the wheel wander that wasn’t terrible but wasn’t a relaxed drive. Now it is! Truck Centers Inc did not have shims to set at 6 so we had to settle for 5.5 degrees which still made great improvement. The caster WAS 2.5 degrees before change.
- I knew our engine had the signs of bad plug wires and not knowing when they were last changed, I figured it was time. I was amazed at the difference. I was averaging about 6.5mpg. I was hitting 7.8 on the way home and oh what difference in acceleration!!
Thanks for the advice on Caster setting and plug wire symptoms. This forum ROCKS!!
