Body mounts: too much weight?
 

I was undercoating the truck yesterday. I went to lower the hi-jack and noticed the body bouncing a little bit as it went down. There is a bit of up and down movement in the rear body mounts.

I haul 1000 lbs of pellets a few times a year. Truck is assisted with air bags. Would this weight be the cause of my worn body mounts?

Has anyone had worn body mounts? I don't think it is a common issue.

The body mount bushings do wear out. I don’t think it’s as uncommon as you think. Plus, your 3rd gen is ~20 years old, and all that weight probably sped up the wearing out.

For the 4th gen, when people install a body lift kit, they often replace the front body mounts because the engine weight wears them out faster than the other body mounts. Some replace all of them when they have the body lifted off the frame. Mine looked ok, so I didn’t replace any of the body mounts.

There are threads on this forum about body lifts that talk about replacing the rubber(?) mounts/bushings.

Thanks for replying. I have been looking for replacement body mounts but seems to be difficult to find. I don't want a complete poly kit that costs $200 nor any junkyard mounts. I went through the dealer parts site but pages of pages of mounts. My phone doesn't bring up the diagrams for some reason.

If anyone knows where to purchase factory mounts please share otherwise I will keep looking.

I've worn out stock rear mounts on a 99 I had 6 years ago, had about 300K, it was bad enough it would bang hitting big bumps. You can replace just the rear mounts if you want, that's what I did.
My current 99 I have Energy Suspension (urethane) body mounts and a 1 inch body lift.

the rear of these trucks have a lot of flex in them. the rear mount also is designed for comfort over heavy sustained use, IMO.

the rear mounts do last a good long time 20 years of service is pretty respectable.

I have replaced 2x 3rd gens now with body mounts. I can share my experience.

replaced all mounts on a 2000 lim with OEM mounts yes this was expensive but you can purchase only the mounts if your hardware is in ok condition.

I would suggest this site, use them all the time. they are great, shipping on smaller items makes it doable.

this site also lists the febest parts and they are much cheaper than OEM toyota, I have used some febest stuff... and yes some of it is junk but I have been running the rear mounts from febest for the last couple of weeks and they seem fine so far.

FEBEST TSBLC95 is the rear mount. @ $18 each

you can get them from 2 @ amazon 24.95 * 2 = $49.90 as long as you can

or from partsouq

5220335250 CUSHION SUB-ASSY, CAB MOUNTING, NO.2 17.88$ * 2 = 35.76$ + 24.46 shipping = $60.22

so either $50 for 2 new febest or $60 for 2 new OEM

Thanks. I will take the hardware off and see if I can get by with just the bushing.

Am I correct in understanding that there are a total of 16 (8x2) mounts/cushions that are needed if you want to replace them all? Looks like Partsouq doesn't have all of them in stock either, which means it's easily north of $300 to replace all with OEM?

yes some have upper and lower bushings. so 18 sounds correct.

It's not free that is for sure. I had similar sticker shock last year when I did it.

Amazon.com: Customer reviews: Body Mount Bushing Set

for $190 all the way around if your hardware is still in good shape is a good deal.

just be careful different years have different body/frame mounts

96 is unique
97,98 same
99-02 same

these trucks are old so... you will have to mix and match if your hell bent on OEM. with a combo of Partsouq, Amazon, toyota parts deal, McGeorge Toyota in VA and my local place I can usually find it. your lucky you live in a place where pick'n pull have non rusty parts. anything going to pick'n pull here in the salt belt is so rusted now it's almost always worthless.

@sleepydad The ES set is available for $180 from Rockauto, and it looks like there are a total of 20 based on the picture. I double-checked the Partsouq diagram you linked and am still coming up with 18... not sure if it's because the Partsouq diagram isn't specifically for a '97 or if there's something else I'm missing.

I think my hardware is in decent shape (truck has lived its entire life in the Southwest / Southern CA). I think I prefer OEM to poly but still doing research on that.

yes variations in the body mounts for different years. they changed the #2 mount in late 98. it's why it shows 2x mount options.

make sure you get the correct set, I have 2 trucks a 2000 and 1997, that set is for a 1997. ES makes different sets.

I have both OEM and poly so I can tell you what I think the difference is.

OEM is a quiet ride and very nice, exactly what you would expect. no surprise here.

poly is firm but not bad, just firm and you get more feedback. not harsh but you can feel more.

my only complaint with poly is when it gets cold (I live in frozen northland) the poly is really harsh. it's like riding on a board. the rubber mounts are harder in the same cold weather but the poly is noticeably harsher. This is only when the temp gets down below 20' F and that might not be a concern being from a warm climate?

this is the one for 2000+

@sleepydad I really appreciate you taking the time to straighten me out and give your feedback! Even though I'm in a warmer climate (for now, at least), I'd prefer to go with OEM if the cost doesn't get too out of control. I'll price it out and make a decision, but again, really appreciate your time and expertise.

Do you know which parts to order for the #2 mount for a 1997? I can't tell from this diagram. The upper bushing looks very different in the two options but both show the same part no. And for the left option, I can't find the part no for the lower bushing (52204B in the diagram).

I just did the rear body mounts in my 99 LTD 173,000mi using Sonoran Steel poly mount for the rear, and it made a huge difference, the old bushings where ripped and clunking over bumps, I have been undercoating and loading my truck up with wood pellets aswell, nothing crazy maybe 20-25 bags a few times a year for the shop, but I'm sure the oil undercoating has killed almost every rubber bushing in my truck, doing LCA bushings now. try just doing the rears, if you remove the rear tires you can reach the rear body mount bolts between the frame and body, these can be a bugger, I used a oxy torch to heat the weld on nuts, and slipped an exhaust pipe over the bushing so I wouldn't burn it while I heated them up, no way would they come out without heat, I soaked them for months to no avail.

the 97 uses the non bolted one, from top to bottom

I'm 100% sure about this mount because I had to deal with this one on my last go around.

if you look @ the same diagram for a 2000 you will see the updated parts. I don't know why they show the parts for a different VIN but restrict the parts to your VIN, they just do it that way. it's stupid and confusing.

Thank you! I'm going out now to try to figure out how much of the hardware I can reuse. I'm lucky that my truck has spent all its time in AZ and CA so hoping I can reuse most if not all of it.

One question about the bolt for the #2 mount: you linked 52217-35100. However, in your link it's -35110. And when I search by my VIN, it tells me it's -35050. Should I just assume it's the last one since that's what my VIN brings up, or is there a specific reason you believe it's -35100?
