1999 Dodge RAM 1500: Strange noise, need help ID'ing
From : ignoramus4143
Q: i have a 1999 dodge ram 1500 with about 70k miles on it 4wd. recently it started making strange noise. the most typical way to make the noise is to start braking from higher speed and slow down to about 20-30 mph. it is hard to say where the noise comes from. it also appears if i just coast at that speed range. sometimes there is more of it and sometimes less. the noise frequency is proportional to speed if i slow down the frequency goes down also. it is rare to appear below 20 mph. i will be happy to do more experimenting and report my findings if necessary i am worried about it. i is there a vibration with the noise try getting up to speed then shutting down the enginedo not lock the column also be aware no power brakes. put the trans. in neutral as well. roy .

roy wrote snipped the only thing that might explain the change that im familiar with is a unbalanced med situation. that is for his family to deal with they have to live with him. roy this is exactly what i was thinking. im glad you spoke up because i didnt. bob bob as you have read this is not a group of timid people. admittedly this is a unusual situation but one we have been through before. please dont hesitate to speak up. yea there are only a few of us timid people here. right and youd be oneg that would be correct. thanks for noticing bfg -- if at first you dont succeed youre not cut out for skydiving .

after 175k nearly-troublefree miles my trusty 97 dakota is being retired from service as a daily driver. a small more fuel efficient car has taken over as daily driver. i have elected to keep my dakota though since its paid off and i still need a truck from time to time. this will be the first time ive ever really owned a vehicle that didnt get driven regularly and im concerned about how to best approach this in terms of keeping the dakota in operable condition. i would like to ask this group for input on this topic. i do realize the battery will go dead in a vehicle that sits for long periods of time thats common sense. im more concerned with things like this - keep it outside or keep it in the garage i have the option to do either. my concern is if i leave it outside like for most of the winter will i increase the chance of things aging faster than if i kept it in the garage im talking about things like gaskets seals rubber hoses electrical components and connections etc. knock on wood my truck doesnt have any fluid leaks yet the bottom of the oil pan and transmission are totally dry. common sense tells me the best thing here is to keep it in the garage for these reasons and also to keep rodents out and prevent sun fading but i dont know from experience just how bad it really is for a vehicle to sit outside for extended periods of time. is it considered ok to leave it sit outside or would that be a big mistake i do check the condition of my antifreeze with a hygrometer or whatever you call it to check the freeze/boil point. - what about the fluids like engine oil ive changed the oil in the dakota every 3000 miles religiously but itll probably get driven less than 3000 miles per year now. should i still change at 3000 miles regardless of how long it takes to rack that many miles up what about the antifreeze and other fluids how well do they age i have thought this through and i hope these dont sound like stupid questions. i do know that i shouldnt ever just start it up move it ten feet and then turn it off. i plan to drive it and let it get up to temperature *every time* i start it now more than ever. i also plan to try to drive it at least once every couple weeks cycling the a/c keep the tires aired up wash the salt off if i drive it in the winter... common sense stuff like that. so with all that in mind i guess in a nutshell im asking this what should i expect from the dakota and what are the best practices to ensure that it will start up next time i need it to its a 1997 4x2 3.9l 5-speed. sorry for the long post and thanks in advance! i would keep it indoors change fluids once a year try to drive it once a week but twice a month should be fine as well. i have an 01 diesel that generally gets driven about twice a month no problems here. its very easy for a retired daily driver btdt vehicle to fall into neglect since you have so little need for it you might want to consider selling it and relying on friends with trucks on the occasion you absolutely need one. .

nah...in this case i guarantee its the plenum leak. although i agree with you and run castrol myself and bardahl the plenum leak exhibits exactly what he described. -- ------------------------------------------ laszlo almasi ----cool toys formerly carolina watercraft works ----mack daddy trailers ----ice angels first thing i think of is poor oil quality. try castrol 20w50. my last vehicle not dodge had a nasty piston rod knock. castrol was the only brand that quieted it. all the other brands were quiet for about two days. -- christopher a. young you cant shout down a troll. you have to starve them. . i get valve rattling on acceleration with the use of regular octane fuel. high octane fuel eliminates the rattle. could timming be a factorsomeone said maybe a knock sensor the motor has 145000 on it and is a 5.2 v8. any comments would be greatly appreciated. .
