Re: noise climbing uphill
Since it happens going uphill, it is likely coming from the rear differential. If it is a scraping sound that increases with speed, and since the noise is under load and not constant in other conditions, it is likely a bearing problem, and not gear related. A shop can pinpoint the location by putting it on a lift and using a stethascope. The only solution is to have it disassembled for inspection. A rebuild kit, including both side carrier bearings and pinion bearings and seals will probably solve the issue, and you are looking at close to $1000 for this, mostly in labor costs. The noise will only get worse, and you don't want metal particles circulating around in the gear oil, damaging other parts. If it is just one bearing making the noise, it makes sense to do all the bearings then, since particulates from the bad bearing can cause the other bearings to wear.
