I had the same problem on My Jetta Recently. At low speeds (10Mph) I got the thump. It felt like the right rear. In order to test this I switched the left front with the right rear. The thump moved to the left front. The tire didn't appear to be separated, but it must have had a flat spot. It solved the problem with a set of Toyo 800 Ultra's. The Goodyear GA's that came on it when I bought it were terrible when they were new, @ 40,000 they were awful. I figured it was best to just replace all of them. Anyway try moving the suspicious tire to a different spot. Good Luck. -----Original Message----- From: Vanagon Mailing List [mailto:vanagon@GERRY.VANAGON.COM] On Behalf Of Steve Cotsford Sent: Wednesday, August 25, 1999 6:40 AM To: vanagon@GERRY.VANAGON.COM Subject: Re: Thump Thump Thump Check to see if you have a wheel which is out of round, ie the tire has a flattened section. Sometimes this can be detected by coasting down a smooth road slowly (5mph) and feeling the vehicle pitch from side to side. Steve |
