my 01 disco stated making a whining noise about 500 miles ago. it has 133k. couldent figure it out but because it is always making strange noises i let it go. now at high speeds it starts to shudder when i give it gas and stops when i let up on the gas. i changed the front dif and nothing changed. i think i need to change the transfer case fluid. any tips would be great. thanks angus.

 

have you had the front drive shaft rebuilt?

 

no. i bought the disco in nov and have put about 15k on it. the dif fliud that i changed was milky. also the dif lock light sometimes flickers.

 

One thing you need to learn real quick, if you have a problem with your truck, you deal with it today not 500 miles later. You probably have set yourself up for a big expense.
How mechanical are you, if not very knowledgable then get your truck to a mechanic ASAP.

 

the milky look is water mixed with the oil in the dif unit. that means there is a way for water to get in and it was submerged in water. not good either way you need some work done to fix the dif units.

 

You might want to send me your tele number, you may have a few issues.

 

i know not to keep driving but i couldnt figure the sound out and because this disco is musical in its sounds i let it go. probably a big mistake. my phone is 214 794 5372. any info on my options or what i should do next would be greatly appreciated. thanks angus.
