C4 BOSE WOES: Repairing & Replacing 84-96 Bose Speakers & Amps

by Chris Petris

lead shot

If you own a C-4 equipped with Bose sound system, you will eventually need Bose amplifier repair or replacement. Every Bose sound system equipped C-4 uses one amplifier per speaker. This is the weak link. Amplifier capacitors are filled with electrolytic fluid which ultimately leaks out onto the circuit board causing failure. If the leak is slow, the amplifier’s circuit board can be damaged beyond repair. Electrolytic fluid is acidic and will corrode anything it touches.

C5 Oil Pressure Sending Unit Replacement

by Chris Petris

If you haven’t already replaced the oil pressure sending unit (CC part # 305254) on your C5 Corvette, it will become a necessity when the gauge stops functioning properly. One telltale sign is the oil pressure gauge needle leaning past the high mark at all times or not moving from the lowest point. Another sign is an oil leak near the rear of the oil pan. Many times, the presence of oil is mistaken for a leaking rear main seal; always look at the top of the bellhousing for the source of a leak. If there is a trail of fresh oil cascading over the bellhousing, chances are the sending unit is leaking. Sending units have an immediately noticeable leak, whereas rear main seals usually experience a slow leak that increases over time.

84-96 Door Outside Seal Strip Replacement

84-96 Door Outside Seal Strip Replacement

By Chris Petris

Automotive door sealing technology has improved dramatically from the early days when rain water came in from all angles. By 1969 GM changed the outer seal strip that wipes the glass clear on those damp mornings to do a good job of keeping water out of the door. In turn it kept water off of the door internals and off the backside of the fiber door panels. By 1984 the door outside seal strip was an integral part of door glass sealing. The downside was they were the most exposed seal strips to date subjecting them to the effects of UV deterioration much quicker than previous year Corvettes. You can help keep them around longer with an application of rubber protectant to replace the rubber solvent compounds removed after each wash job. Products like Adams V.R.T. Vinyl Rubber and Tire Dressing from Corvette Central P/N 106824 will keep your outside seal strips looking good for many years. This dressing brings back that new look without that greasy oily slick look, you can also touch it without fear of it coming off on your hands or clothes.

1997-2013 Rear Anti-roll / Sway Bar Link Replacement

1997-2013 Rear Anti-roll / Sway Bar Link Replacement

By Chris Petris

When we had a chance to look under the first C5 in 1997 it was hard to believe a performance vehicle would have a plastic anti-roll (sway bar) link. To make things difficult lock nuts were used to hold the links stud into the control arms. That meant when someone removed the end link chances are they would rip the joints seal because they did not hold onto the stud during removal. The original plastic sway bar end links flexed under hard cornering making the anti-roll bar less beneficial. Of course a hard driving Corvette owner might break one or more on a track day. By 2002 GM finally dropped the plastic pieces replacing them with an aluminum anti-roll bar end link. One of the few things that did occur positive is the same end link is used from 1997-2013 so you can easily find and replace the weak original 1997-2001 links. If someone was not being careful and tore the end link seal during suspension service you may need to replace one or more on your 2002-2013 Corvette.

Corvette Central has the anti-roll bar end link you need in stock form or heavy-duty performance Heim joint style end links. The installation is simple and does not require much time or many tools to complete. We often replace the end links when replacing shocks making a simple job even easier. The most important thing to remember when replacing the end links; the wheels should be hanging free on the front or rear. If one wheel is hanging free and the other wheel is loaded the end link will also be loaded making it difficult to remove and possibly dangerous. This is not something you can do by jacking up one side of the Corvette at a time; it must be done with the front or rear jacked up. The following photos will show you how it’s done.

An 18mm wrench is used to turn the nut while a T40 Torx bit holds the stud. Of course you can spin the stud on the old pieces for removal.
